For the most part, Nethfel has actually given you a MORE detailed version of what you'll need that you most likely will actually need.
If your computer connects to the internet via an ethernet cable, then you would probably want to power-down your modem and your router, connect the Mac to it, and then power up the modem, then the router, then the Mac. It should find everything automatically.
For wireless, it's even easier. The setup routine you'll go through automatically when you turn on your computer will detect local wireless networks, offer you the choice to connect to one of them, and ask you for the password (if there is one). That's it.
For your email, Apple's Mail "setup wizard" is already familiar with all the major email providers (GMail, Yahoo, AOL, Earthlink et al) and will figure out the POP/SMTP or IMAP settings by itself if you use one of those services. Otherwise, you will need your POP/SMTP or IMAP settings, which you can find on the support page of your ISP's home page (or just google "[provider] email settings"). And of course your username and password as Nethfel mentioned.
Don't overthink things -- that's the PC way. You're on a Mac now.
