Billy,
The 003 is pretty straightforward and easy to use. It's just a firewire interface. Unless you really want to be able to physically move the faders I would recommend that you go with the 003 rack.
Now, Protools is another matter. It is the software that ties everything together and allows you to edit and mix your tracks. Unless you are a whiz at learning software, I'd recommend that you find someone near you who offers courses or seminars in Protools, or at least someone who can help you get started and answer questions as they arise (and they
will arise).
At the very least get and study a good reference book for PTLE.
Protools is the best DAW software going and once you start to learn it you'll be amazed at the things you can do with it.
I'm pretty proficient with Protools and will be glad to answer any questions I can.
Good luck!
