I just installed acbPowerMeter (you can find the cab on the site if you search) to track my battery discharge rates. This is a good way to see what is going on, though it will not pinpoint the source. It will create a time/discharge rate plot, which is very helpful. Post your peak and average values to see if you can get some feedback.
I also set my mode of operation in the "phone/network" section to "CDMA only" rather than "Global", so it is not searching for GSM towers. Finally, I uninstalled one app that looked suspicious and turned off the GPS function in another. That seemed to get my battery drain problem under control.
Good luck!
