Some pictures would definitely help. The 2nd O-ring is a spare that comes inside every DRE pump. "The pieces scattered about" has me a little worried. My guess is your handle assembly may have broke, which can be replaced if that is what happened. If you are local, you should take it over to DRE and let them have a look.
One a related note, you should perform routine (once every year or two) maintenance on any of the more expensive pumps. You should remove the handle assembly and clean all of the dirt/sand/grime that accumulates inside. Then re-grease with vasoline or equivalent as well as replace the O-ring periodically.
