I photograph a lot of events in badly lit spaces. I will try to use Custom WB, but the other problem I have is consistent underexposure. The flash (Speedlite 550 ex) either does not recycle quickly enough, or, most likely, just doesn't read the light properly. I am using rechargeable AA batteries.
Would a battery pack make a big difference? If so, which one?

When you say events, just how far away are you from what you are photographing. If it is a concert, flashes do not work from a distance.

No, not concerts. groups of 3, 4 people. distance is not an issue. I have had problems even with low white ceilings, that I thought I could safely use for bouncing the light. I am having this problem especially in dark spaces, without indows. Restaurants for example.

Try upping your ISO, pulling out the diffuser (for the 17mm setting), putting your camera on "p", and bouncing the flash off the ceiling. This is what my camera is set at for wedding receptions, and it works surprisingly well.

Thanks, I'll try. You think pulling out the diffuser is better than the diffuser that covers the flash? And what happens when the ceiling is very high?

To get softer light you need to increase the surface area of your source. The diffusers help, but not much. Bouncing off of the cieling, when aplicable is great, so long as it is white and not colored.
The Lightsphere II by Gary Fong is a nifty accessory. It is basically a big ol' plastic ball that diffuses and softens the light. You can shoot directly at someone without getting harsh shadows or overexposure.
I would recommend getting one.

I think you'll be surprised at how high a ceiling you can get away with bouncing from. The reception I shot this weekend was in a ballroom with pretty high ceilings, and the bounce worked really well. Upping the ISO is what allows you to get away with it... By the diffuser, I do mean the built in one that covers the flash and allows you to use 17mm lenses.
