very nice, you should process it in PS however. lower the brightness and play around with the contrast. Should result in some nice pictures. What kind of camera were you using? Nikon D40?
that's a great price for the specs you've gotten! Do you really need a T7500 processor though? Not a lot of people need more than a T7300 I would assume.
I recommend reading and following my guide that I've written on NBR.com

it's a lot of pictures, but it ensure you're doing the right thing. It's baby steps
Vostro's are good deals so long as you don't upgrade them too much. Once you do, you're better off finding an inspiron coupon and applying that to a home purchase.
