OS X is 64 bit. As far as Windows 7 goes, 64bit offers more security features that isn't a part of the 32bit ISA, so definitely go for the 64bit edition. Plus, if you choose to install Windows 7 using bootcamp, you'll be able to take advantage of all 4gb's of RAM.

I'd imagine you can install 64-bit. My older MacBook Pro (with Core 2 Duo) was able to run Windows 7 64-bit.
