Honestly, when it comes to the cheapy stuff-drums are drums are drums. They're all inexpensively made. You're not going to find a fundamental tone etched into the shell like you would with a DW kit or something. I'm not saying this is necessarily a bad thing. For the most part, good heads + good tuning + good drummer = radness. It doesn't matter how much it costs.
If I had $600 to spend on a drum kit, I would buy a cheaper kit (here's one for $199 http://www.musiciansfriend.com/product/Pulse-5Piece-22101214-Drum-Set-with-Hardware?sku=445758 ), and spend the extra money on nicer cymbals. Why? You can tune a drum, but you can't tune a cymbal. After spending $70 on new batter side heads (the stock heads are crap-and they WILL make your drums sound bad), you would still have enough to buy some faily decent cymbals ( http://www.musiciansfriend.com/product/Zildjian-ZXT-Rock-4Piece-Box-Set?sku=443914 ). Trust me-as a recording engineer, I've had all kinds of drummers come in with all kinds of kits. The worst budget kit with good skins, proper muffling when necessary, and good tuning will sound better than the best kit with the worst tuning. Those crappy Camber/B8/ZBT/Pearl cymbals ALWAYS sound bad.
Get an experienced drummer friend to come over, help you reskin it (immediately-those other heads will sound awful and the coating from the snare will end up on your cymbals), set it up, and tune it right. Get them to show you the proper way to hold your sticks (so important), heel-up and heel-down pedal methods, and few basic rudiments and practice exercises. I know you say you're "pretty skilled"; but you don't own a kit and haven't practiced nightly for years, so there's always something to learn from the more experienced. Humility is a good lesson when trying something new.
Good luck. I hope the investment proves worthwhile.
