If you want a beginner lighting kit get a couple Yongnuo 560 III (make sure to get the III) at $70 each, and a YN 560-TX transmitter ($50). If you want to save $30 you can get the RF-602 or RF-603 transmitter, but the one I mentioned is worth it. It's not going to get much cheaper than that, and yet it has features that systems three times as much don't have. You'll eventually need stands and modifiers but you can start with the little plastic feet that come with the flash and sheets of white posterboard.
Once you start really looking critically at glass photography you'll notice that you don't eliminate reflection, you just control it. Without reflections you wouldn't see anything, unless it's colored. Even then, well placed reflections add dimension to the photos. Once you get more advanced you'll probably find out that for truly clean images good lighting is only half of it, the other half is done in Photoshop.
Get a basic lighting kit, go over to Strobist and start learning:http://strobist.blogspot.com/2006/03/lighting-101.html
And then grab your glasses and practice some basic rim lighting, like most all of us did when we were learning flash. It's like drawing an orange in art class, everyone starts with the basics.
