My goal is to upgrade to OS X version 10.6.8. If I go to apple and purchase OS X Mountain Lion, will I be able to get this version? I need this version in order to update to iTunes 7.0 and put my music onto my new iPhone 5...

You can't purchase Mountain Lion from a Mac OS X version older than 10.6.8. Since you also need at least 10.6.8 to run iTunes 10.7, in this case it doesn't really matter whether or not your computer can be upgraded past it.

The models Late 2006 Core 2 Duos 2,1 through Early 2008 4,1 can only run a maximum of 10.7 Lion
The 10.6 Snow Leopard DVD is back in the Apple online store. You can now get it without having to phone the store.
Once you are at 10.6.8 Lion is still available from Apple. You will have to call Apple Customer Care 1-800-692-7753 or 1-800-676-2775. to purchase it. Then within 3 days you will get an email with a code which you can use to download Lion from the App Store. The price is $19.99.
Lion will require at least 2gb of RAM but really needs 4gb to run smoothly.
As for third party programs see this list for compatibility with 10.7 http://roaringapps.com/apps:table
Also Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.
