Mbox mini advice

I just picked up an Mbox mini, and it's really cool.
Anything I need to know about it or Protools that might not be in the manuals or dvd that came with it?
This is also my first time using Protools, and I can say it is a lot more intuitive than the version Cubase my band uses to record.
It also came with a load of free plugins, any that are really cool, or really worthless?
I already loaded up the Amplitube LE, and am downloading the Ampeg thingy for it.

Oh, and I'm running everything on a 2 GHz Intel Dual Mac with 1 GB of ram.
