Answer 1

The answer to that question depends as much on your goals and expectations than on your system type.
As for an option that's received wide note of late, the GitX GUI-version of git.  That might be easier for you.
From that list you've linked, your choice is 32-bit or 64-bit (your Core 2 Duo is 64-bit) and your software version; whether you are running 10.5 Leopard, 10.6 Snow Leopard or 10.7 Lion on that MacBook.  I'd expect you can run the recent 64-bit Snow Leopard variant.  (I'm somewhat surprised there's such a warren of git installers posted, but that complexity and how that might be reduced is another discussion.) 
As for some of the notation in that list, i386 is an Intel binary, and (in this context) 32-bit, and x86-64 is also Intel, and 64-bit.  The rest of that string is the git version, and the target Mac OS X version.
