Creatine is over rated imo. I prefer glutamine cuz i feel the difference in energy levels, but all you really need after a workout is protein powder, sugar (gateorade, juice etc.) and water.

As far as pill vs powder, id go with the powder for sure.

FWIW ive been crushing again (weights/biking/running etc) since May and just started working at UPS. I load and or unload trailers (ie lift boxes) all night, which is very fast paced hard work and is definately getting me in even better shape than just working out.
