Help with Tivo

So....my wife got a Tivo from her company for her birthday.

I know what Tivo does in general, but what can I do with it and my PB?

I have a wireless network at home (802.11b), so will Tivo recognise that? Through Rendezvous?

Or will I need to buy a Bluetooth dongle.

I want to be able to make the most of it, and I'm sure there's a bunch of people here who know a whole lot of Tivo goodness.
