Why oh why are you playing with 40-50 bb? your stack size makes the second hand an easy call, but that's irrelevent.

As for the first hand, I play the same without a read. Limp reraise says "I want to make some money with these rockets/cowboys."

Edit: oh and I don't think you suck, these are reasonable plays. But if you are 'rolled for the limits, buy in full.
