Why not 64-bit? Running on a processor incapable of 64-bit processing or below 4GB of RAM?
I am not pushing you to get 64-bit, but if your computer has 4GB of RAM, and a x64_x86 processor, then you should really consider getting 64-bit.
But since you didn't provide specs, I don't know what would be best for you. 32-bit is probably better in your case I'm guessing
I also agree about the 64 bit thing. By buying a Windows 7 license instead of waiting to inherit it via a new computer, I assume that your computer is fairly new and would benefit from a 64 bit OS. Beside expanding the ram limit, there are real benefits to using a 64 bit OS whether that be the new OS X 10.6, or in this case Windows 7.
Also, 64 bit OS's have matured enough that you shouldn't run into too much compatibility problems. Anyways, every windows 7 license key is for a 64 or 32 bit install, so its an relatively easy choice.
