I don't have a 580, but I do have the Speedlite 430 and Canon 40D. It was my first flash I bought about 4 months ago.
Truth be told, the flash operation is a hell of a lot easier than I thought it would be. Once I learned the nuances of bouncing flash, I almost *always* bounce flash.
I got myself a Sto-Fen diffuser on the head, which I use most of the time with a 45-degree bounce. I keep Hi-speed sync on, and in dark situations I use fixed 1/250sec exposure in A-priority mode. In bright lighting I switch "Exposure" to auto and double-check to make sure Hi-speed sync is enabled. In darker action shots, I enable a high ISO but fixed 1/250s to help get more of the background illuminated if I want it while maintaining action freeze. For static shots with a desired background illumination, I just switch "Exposure" to Auto and shoot from a tripod. Great way to get pseudo HDR for some shots. I wish I had about 3 flashes and a wired 580EX (or Canon would stop being cheap pricks and just enable flash commandering from onboard flash)
Once you practice with how various settings give you varying lighting results, flash work isn't nearly as hard as people make it out to be.
