Are there Mac versions of virtually every windows program availible?
No. But there are a lot that can be run, you'll have to do a few googles on that one.

I'm in programming classes at school right now, is a Mac able to run programs like Visual Basic, JCreator, and other compilers?
See previous answer.

I have a Wireless network set up in my house using a microsoft base station. Can I hook a Mac up to that network?
Yes.
