What you could do is dist-upgrade to either testing or unstable, with testing being the best choice, then it should install and if needed you can do what is called apt pinning and get the odd package from unstable. Now whether you want to do this I don't know but if you want I can give you a hand getting the proper settings in place so it should work. Another option is just getting the Debian source for the package(s) then build them yourself and installing the resulting .deb files with dpkg if they don't have a hard dependency on on some package in testing/unstable (eg must have new feature in libc6 for instance) then they should be able to be built for your install then they will just work.
Another thing I see looking back here that you have the backports in you sources.list. So what does apt-cache policy libcompizconfig0 show you? If you see that it is at the backports site then you will want to remove/comment out the unstable line then update and try to install from there the work of building the packages for a stable install would have already been done so it should work fine.
Ahh, that makes sense. I had to install libc6 in order to install the NVIDIA drivers but I see where I installed the "stable" version and not the "unstable" or "testing" version. So I'm assuming I need to change my repos in order to get a "testing" version? Which repos would that be?
Sorry, I'm not used to Debian, but more of Ubuntu where a lot of things are already installed/taken care of lol. Still got a lot of learning to do! But hey, what are forums for anyway?
