Need some help getting started with speedlights/ strobes

So the other day a friend asked me if I wouldnt mind taking some photos of her, along the glamor/ nude lines. And since she's pretty hot I said sure..

Only down side is about 6 months ago I sold all my gear to pay for school. And I just recently got a new 50d w/ kit lens, a 50mm f/1.8, and a set of cybesync's. So I need to spend some $ prior to the shoot for lighting. But here is where I'm stuck.

My first thought was:
(1) 580 exII
(1) light stand
(1) swivel
(1) 45" unbrella
(1) 22" reflector gold/ white
$450 - This would give me a basic off camera, or on camera setup.

2nd thought was:
AB Beginner setup
(1) 430 exII
(1) cybersync (additinal)
$660 - this would give me a 2 light setup. While still giving me an on camera flash. But is more expensive. And with the AB's a bit larger to move around.

3rd thought was:
AB Digi Bee setup
(1) cybersync (additinal)
$660 - Also provides 2 lights in a little better setup I think.

So yea I'm cant make up my mind. I kind of leaning towards #1 just casue of cost and because at some point I'm going to need a good camera flash.

I think option #1, great place to start and gives you a lot more initial flexibility...you are missed a few key pieces that you need for a shoot in the other options. I'm running exactly what you have in option #1 except I have 2 of everything.

So basically $500-$600 to take pictures of a hot girl and maybe some. Why not rent the stuff and see how it goes?

LOL.. I guess you could put it that way.. But buying a flash like the 580 is something we all end up doing anyways. So kind of how I see it at least for the 1st option.
