Multi tableing helps to keep me tight b/c I don't get bored and play stupid hands... Try adding another table and see if you can handle it... I would stay at .01/.02 until you get the hang of it.
Sounds like you are playing the right set of hands, just play the lower quality ones cheap and into multiway pots. Play small pairs cheaply for the set. Work on finding your leaks, not just where you lose too much money in a pot but where you don't get the maximum out of winning hands.
