well, if you haven't already, check the Equipment buying guide at the top of the thread.
As for the Stanton Scratch Pack...I've used the STR8-60s that come with that set and I don't like them at all. I'd reccommend just saving your money.
As for buying records, the easy thing is head over to
www.turntablelab.com and get stuff from there. Other than that and other online shops you can check around your neighborhood for thrift stores, pawn shops, record stores, etc. and start digging.
