All modern processors (except for some celerons and maybe semprons) support 64-bit so you shouldn't have to worry about that.
Now about 64-bit, I have it and I like it. All my games work and most of my programs do. The only trouble I ran into was that my printer doesn't support 64-bit, and Itunes won't burn cd's or import cds. Also, my friends Iphone does not work with his computer running 64-bit. Everything else works fine.
I decided to use 64-bit because I want to keep my system going for a few years, and it lets you get past the 3.5gb of ram (or whatever amount it is) restriction. Also, I want to eventually get a quad core processor, and I heard that they don't run to their full potential unless they are running under 64-bit.
So, I would just say check all your important devices like printers, cameras, and other peripherals to see if they are 64-bit compatible, and make a decision from there.
