Are you talking about using a bracket to move the flash a bit away from the camera?
Thanks.
Radio triggers and light stands.
They don't have to be super expensive. You can get a pair of good sturdy light stands for $40
and a set of radio triggers for $100 (for three Cactus V5s) or even much less (if you go with older Cactus models, or Yongnuo, or Cowboys).
A Super Clamp
is a great idea, too - lets you put a flash where a stand won't go.
Put two or three or four flashes around the venue, do a few test shots to make sure you're getting even coverage and good exposure, and you're all set.
Two hundred bucks worth of inexpensive lighting gear can really step up your results to the next level. You've got one Speedlight so you're already on your way. A couple of YN-560 speedlights to complement the 580EX, some radio triggers, and some grip gear, and you're there.
If you get YN-560s, you can even set them to optical slave mode, so you only need one trigger and one receiver (as opposed to one receiver for each flash). Heck, you might not even need any triggers, if they optically trigger from the 580EX on your hot shoe. The down side of that, of course, is that they'll fire every time Uncle Bob uses his flash .. or even any time Granny Mabel snaps a flash picture with her point-n-shoot.
