All of these posts are great advice for somebody with photo experience...
But messing with changeable lenses, lights, and color balance are only going to confuse you.
I think you'd be best suited with a high quality "point and shoot" camera. Forget about buying lights until you have some real photo experience. For now, get used to working with models and making sure they have fun. Single girl sites are great for taking candids. Go to the park, mall, lake, etc.. Just take fun snapshots and get a few good closeups
Check out the canon cameras in the $350-$500 price range. They take good exposures and you won't have to mess with a bunch of buttons that you don't understand

If you get serious about photography and start making some money... you can buy professionla gear LATER. For now, a high quality "point and shoot" is all you need.
Honestly, I have a good friend that runs several single girl sites... He makes about half a million dollars a year in sales and shoots with a 500 dollar camera.
But he's got HOT models and knows how to make the pictures fun... He spends a lot of time on location and in real life situations.... he gets lots of great candids
A single girl site needs video to upsell... get a decent DV camera too and you're all ready to go
