Help: How to connect Eleven Rack and MIDI keyboard?

[el biciclista]

My son wants to:
(1) Record guitar tracks and
(2) Create the other tracks using loops, MIDI and virtual instruments.

He has a MacBook Pro laptop computer.
I have a Pro Tools HD system, so I'd like to keep him in the Pro Tools family.

He is looking at an Eleven Rack for the guitar input, and a simple MIDI keyboard like the Oxygen 25 for creating the MIDI tracks to input to virtual instruments.

Here are some basic questions, since I'm not familiar with this gear:
(1) If he buys Pro Tools 9, can he connect the Eleven Rack and Oxygen 25 directly into Pro Tools 9 via USB, or does he need additional interfaces?
(2) Could he go with something like Fast Track rather than Pro Tools 9?
(3) Is Oxygen 25 a good choice for a basic MIDI controller?
(3) Does the MacBook Pro have enough horsepower to handle this?

I probably have posted this in the wrong forum, since I am asking about Pro Tools 9 (although M-Audio is maybe an option). So, I'll also post in the Pro Tools 9 forum.
But I'd still like to know if Fast Track is an option to handle Eleven rack and a MIDI keyboard.
Thanks!

OK, I've gotten the info elsewhere:
- Eleven Rack comes with Pro Tools LE 8
- I can connect a MIDI controller into the Eleven Rack MIDI In.
