1. It isn't possible to buy Mountain Lion from Mac OS X 10.5.8 or to use it to directly upgrade a 10.5.8 system. Upgrading to Mac OS X 10.6, which is available in the online Apple Store, must be done first.
2. Noting #1, no; back up the content anyway. If you choose to erase the partition before installing Mac OS X 10.8 on it, yes.
3. It depends on what the requirements for them are.

Thanks for getting back to me. I will try that and have a look. I have to upgrade to use my iphon 5 and new adobe programs. Would I lose my programs if I went up further (I wasn't 100% sure what you ment and am just looking for clarification)
