jaybass, you didn't say if you had an intel Mac. If you do then you are golden. If you have a G5 or older machine you are going to have problems. Most software for those systems are no longer produced.
However, even if you do have an intel Mac you are faced with how you will implement a Windows instance. Your choices in decending order are:
Parallels or Fusion
For Boot Camp, Parallels, and Fusion, you will have to purchase a copy of the Windows OS. I would recommend Windows 7. However, Boot Camp is not going to support Windows 7 on certain intel Macs.
Parallels and Fusion will run any flavor of Windows OS. The advantage of these programs is that you don't have to boot into either Mac OS or Windows. You boot into Mac OS and run Windows in the virtulization environment.
CrossOver is a Wine implementation on the Mac. It has the ability to run without a copy of the Windows OS. It is the cheapest method, however, it isn't that great for games, and you may experience some problems with esoteric Windows software. Your mileage may vary.
