bactrack, now what?

I got backtrack installed and working.  Now what?  I've never used any of the tools supplied with backtrack.  Where's a good place to start?

Imagine I'm travelling from A to B, and I'd like to log a list of all wifi networks, and some details of those networks. (encrypted? type of encryption?)

The bad question is: "How do I do that"
A better question is: "How do I find out how to do that using backtrack, since asking here probably isn't going to help"
