First 2 refer to the O2 sensors and are probably caused by the last one "Fuel system lean during acceleration." Cheak for airleaks around MAF and more likely intake gaskets. Good luck and try not to drive it too hard until you resolve the issue.

Pete, gently clean the MAF sensor wires with a q-tip and alcohol or spray them with electrical contact cleaner. Dirty MAF sensor wires will cause those three codes with the P0101 MAF sensor problem code showing up a while later.
