Right-clicking, etc in Windows

I've just installed Windows XP via Boot Camp and so far am really impressed. It runs a lot better than Windows does on my old PC laptop! The only trouble I've run into is trying to figure out how to right-click in Windows. The two-finger click on the trackpad that I use in OS X doesn't appear to work, and additionally I don't seem to be able to tap on the trackpad to click either, as I can do in OS X. Is there a way to fix this? I assume some keyboard shortcuts must be different as well. Mainly I'm looking to find out how to right-click.

Thanks.
