Staying disciplined with the hands that you play will be a huge key to your success in play money. You can add a few other hands if you want as well such as small pairs (22, 33, 44, 55), suited connectors (JT, 98, 87, 76), and suited aces (A9, A8, A7, A6, A5), but you should be folding pretty much everything else before the flop.
