Shooting in and near Las Vegas

Hi there everyone-
I am going to be shooting a music video for 3 days in and around Las Vegas. I'm just wondering: I need to pick up a few supplies, compressed air, an LED video light (not sure which one, suggestions??), a light stand for balancing the Glidecam (things I can't fly with etc), and would like any advice as to a great STORE in Las Vegas to buy some of these items may be.

Thanks!!
Luna
