Okay, if you can believe it, I finally made a decision and ordered one tonight. I ended up going with this:

I went with the high pressure system for two reasons: 1) A more compact and weight saving gun, 6lbs vs. 9, and 2) Simply because I couldn't pass up the deal.
I was going to go with a clipped head nailer anyway, so the fact that it's going to be smaller and lighter is a major plus.
The entire kit retails for $1,020.00. I ended up buying everything from Amazon.com and got the Porter Cable kit, plus a DeWalt 6.5amp reciprocating saw w/ 10 blades, and 2 day shipping, all for $465.00
Just the nailer and saw alone would have exceeded that price, and I got a 175psi compressor, hose, fittings, and saw blades basically for free.
Thank you all for your extensive help. I apologize for all the newb questions, but now I know and will be able to pass along this great info to another person in need. Aside from the fact that I can't wait to start rebuilding!!
So, again, I can't thank you guys enough, and I'll post some pics of the gear when it all comes in, which is supposed to be Tuesday.
Oh yeah, here's my new saw too!

EDIT:
Wow, the deals just keep coming from amazon. I just placed another order with about $400 worth of levels (48", 24", and 9"), plus a few hand tools, and got it all for $110. I'm doing all my tool shopping from amazon from now on. The trick is taking advantage of their deals though.
