First things first... You need to make sure that your system is capable of running Mountain Lion. First and foremost, since you're running 10.5, we need to make sure you have an Intel CPU in your Mac. Then it needs to be at least a Core 2 Duo, but more than that you'll want to check Apple's website for a list of older models that were left behind at 10.7.

Beyond that, there is no real upgrade path. You can try upgrading, but there's a very good chance that it will not go well, so be making with the backups and make sure you are ready to do a clean install. Also, make sure you don't have any old PPC apps around that you cannot afford to live without. Starting with 10.7, Apple dropped all support for Rosetta, which provided PPC binary compatibility. So far as I know, no one yet has developed a third party solution to that.

After you've done all of the above, you can start worrying about getting a copy of Mountain Lion to install.

not all C2Ds can install ML. The late 2006, and early 2007 C2Ds, can only go as far as Lion. ML requires a 64 bit processor.

All C2Ds

All C2Ds are 64-bit CPUs. It was the Core Duo and Core Solo that were 32-bit only, the Core 2's were all 64-bit, but they didn't have a 64-bit EFI was the primary issue as I understand it. Given how forthcoming Apple tends to be with details, I'm just throwing darts in the dark with only a vague idea where the target is though. Wouldn't be at all surprised if the real reason was that they were about to hit Vintage or Obsolete status, and so they didn't want to open themselves up to the possibility of having to support them even just on the software. It could even be the somewhat more sinister planned obsolescence, or Tim Cook throwing a temper tantrum like his late mentor taught him, though he'll probably never have anything on Steve Ballmer.
