Using disc utility i erased the top level entry and the 2 partitions below it called "untitled" and "499.76 GB"
I then used Disc Warrior to rebuild the top level and the partitions.
Disc Warrior then rebuilt and replaced "untitled". Disc Warrior says:
Also FWIW, if you erase the disk, there is no need at that point to use DW - it's empty, it's been erased, so there's really no need to rebuild anything. (I didn't know you had erased it).
Important (because I'm not clear on that):
So, you now have a completely empty external hard disk, properly formatted, and divided into how many partitions?
If it is just one partition...... (and I'll number my answers to correspond to your questions):
1. Yes, you can use CCC to make a bootable clone, but: CCC does not make a partition. You need to use Disk Utility to partition the drive first. Simply go to DU, click on Partition, click on the partition layout and choose the number of partitions.
2. no need to use Time Machine if you don't want to.
3. You can do that; you decide how much you want on there (besides the basic OS); I have one that I call "fresh" = a pristine install of the OS plus a fresh install of all my apps, which means if there is a disaster, I can start fresh; the only thing missing is my Documents folder which I can simply copy over.
4. You can choose how many partitions you want on the external; for your bootable clone, make it large enough to hold your current system plus at least 40 GB more for future increase in size. So you decide how large each partition will be; looks like you already know you want 200 - 300 for iTunes stuff.
5. So your internal has two equally sized partitions and HD has the OS + other stuff on it and HD2 the users folders?
6.
I assume CCC will partition
No. See above - you need to partition first. Yes, CCC will clone the HD - I'd make about 100 GB (figuring in future growth). Adding this tip:
When you partition, name your partitions - it'll make life a lot easier, i.e. your Macintosh HD clone: call it "Mac HD clone", your user folders "Users" or some other name you can identify quickly; iTunes: "Music" or Videos or whatever.
7. Name that partition and then use these articles to move your iTunes and iPhoto libraries (also iMovie in case you have anything there):

Make sure everything works on the external before wiping that stuff from your internal! And, remember, that now your external is your only file of these things, so you need to back them up somewhere else...
8. How about you first put another CCC clone of your system on that partition (name it Mac HD ML). Then download ML; before the install begins, dismiss the installer. First, find it in the Applications folder and make a copy of it (for future use) and park it somewhere else - reason: the installer self destructs after it is finished. Also, copy it to your partition (desktop is fine). Then boot into that partition and launch the installer.
I think I covered it all.......
