As many have advised by now, you should stick with some simple and regular picks before getting into slimlines (which are very fragile). I was hoping you'd search around for some other similar threads but I guess I'll indulge this time.
Your best option are the $1.49 "Plain Ripple Handle" (PRH) picks from Southern Specialties at
www.lockpicktools.com. Get yourself a small hook, medium hook, large diamond, and then anything else that is to your liking. As for a tension wrench, I highly recommend the long twist-flex.
These tools are the first and foremost tools I use, not only in sport picking, but in my profession as a locksmith. They are simple and get the job done, and the ripple handle keeps your fingers from bleeding.
