Well the definition of straightforward is a matter of opinion. I'll pop up that image again just so we can be clear how iTunes organises everything if you let it...
iTunes 8 lumped all the artist folders at the level of *iTunes Music* along with some special folders for things like Movies, Podcasts, TV Shows etc. In addition iPod Games & Mobile Applications were stored up in the main iTunes folder which has some implications when it comes to separating the content of the library (stuff outlined in red) from the database & cache files (everything else).
iTunes 9 introduced something called *iTunes Media organisation* which basically recognises rather late in the day that iTunes is no longer just a music organizer. Not only does the new layout add clarity and structure but now that all the "media" (including stuff like Mobile Apps) is inside the iTunes Media folder it is much easier to move an iTunes library from one place to another, i.e. restore from backup to a new system, without it breaking. Content outside the red box generally won't work after such a move.
Whether you like the iTunes layout or not, everything that it is responsible for creating or moving around, e.g. CD-rips, store purchases, consolidated files, podcast downloads etc. will be placed in that layout. If you want to take on the extra work of organising things your way then turn off the *Keep the iTunes Media folder organized* and *Copy to iTunes Media folder when adding to library* options, put your files where you want them and drag them into the library. If you want to rearrange anything already in the library, delete it first, move it around and then add it back again, or be prepared to reconnect the files one at a time. Or, if you're really ambitious, do what I did and write yourself a script that encapsulates all your personal organisational rules, renames the files accordingly and then reconnects iTunes to them before it has even noticed that they've gone. Note this is
not what I'd recommend - if you can, surrender the organisation of the files and the folders to iTunes and get on with watching/listening to your library instead of obsessing over how it is set out in Explorer/Finder. If you still want to organise things your own way then I still recommend you so within the general structure offered by iTunes 9 and at the very least inside the iTunes Media folder so that you can take advantage of "portability".
Going back to your original post...
Music folder has sub-folders of Amazon, iTunes and Music (and 3 desktop.ini files - do I need all of these? what are they for?)
The Amazon downloader has various options controling where it puts the downloads, I guess you've let it create its own folder. iTunes is for... iTunes. Not sure how you got another Music folder in there, something you dragged in by hand perhaps? Any windows folder with "special" properites or custom icons, e.g. "My Music" will have a desktop.ini file. In addition if Windows Media Player has scanned the folder for media files it too creates desktop.ini files. Folders with artwork also get Thumbs.db files. These are files are normally hidden.
Amazon folder has 4 folders of songs I have bought (seems as it should be)
If you are using iTunes as your main media library (whether it's allowed to organise the files or not) point the Amazon downloader at \iTunes\iTunes Media\Music\ for best results.
iTunes folder has folders for Album Artwork (is this just for iTunes?), iTunes Media, iTunes Music and Previous iTunes Libraries
*Album Artwork* is an artwork cache and is part of the library. It will be recreated if removed.
*iTunes Media* is where your media should go. Check that *Edit > Preferences > Advanced* shows this as the media folder.
*iTunes Music* is where your media should have gone in the past. Use *File > Library > Consolidate Library* to
copy these and any other scattered files, e.g. those in the Amazon folder, to your main library folder. Because the process copies files rather than moving them you have to delete the now redundant originals by hand.
*Previous iTunes Libraries* contains a backup copy of the previous iTunes library made during each iTunes upgrade. If for some reason the upgrade fails or you need to roll back to an earlier version of iTunes, you can use these files.
Music folder has Amazon folder (which has 3 or the 4 songs mentioned above)
Anything here that is in your library would be copied by Consolidate, if they're not already in your library, or dupes, move them to the *Automatically add to iTunes* folder.
So back to the iTunes folder above...
iTunes Media has has a folder called Music and in this Music folder are some of my albums
Which is the way it should be, at least according to Apple.
iTunes Music has some of my albums as well.
A legacy of having upgraded and perhaps having created a fresh library under iTunes 9. Normally the upgrade process would have retained the earlier iTunes Music folder but put the iTunes 9 layout inside it. If you decide to consolidate into iTunes Media this folder will contain dupes you can remove, assuming of course all the files were in the library at the time of consolidation.
So why are my iTunes albums saved in different folders and why are my Amazon albums partly duplicated in different folders?
A number of different bits of software with different settings at different times.
And how can I get all this lot into just one folder or into some better order?
Initial instuctions above... Decide what you want to do and either move everything around by hand or get iTunes to consolidate. For everything not inside the iTunes media folder check that there's a corresponding copy in the library or that you really want rid of it before throwing it away.
For general tips on getting your library organised inside iTunes itself see

After you've finsihed letting iTunes move things around, or even if you don't, you might find there are empty folders or folders that have orphaned artwork. These often get created by Windows Media Player and get left behind when files are reorganised. See
http://samsoft.org.uk/iTunes/CleanDeadArt.asp for a script to tidy things up.
