A big reason to select the Pro over the Air is that I infer this machine has got to last you 2-3 years, perhaps more. I'd recommend getting the most powerful machine you can. The MacBook Pro is a bit faster than the MacBook Air (even though the Air is quite fast). As far as weight...you're a guy. 4.5lbs vs ~3lbs. Not a tremendous difference there. The Pro offers better expandibility as well. The Air is nice machine, but I'd not let the slight weight savings be the driving push to get one.
Again, I've had both machines and they're both nice.
