go on ebay and buy a bunch of used casino playing cards.
If you're going to be playing 6 deck games, buy 6 matching decks, also buy a few single decks and keep them in your pocket. you can practice counting anywhere, at lunch, over coffee, on the can! watching the tube, wherever!
#1 Basic Strategy
#2 Counting speed and accuracy
#3 True count and deck estimation (if it applies to your system)
#4 Bet Ramping
#6 Index memorization
that would be my list of important things to learn and in the correct order.
buy a few books on counting, $25 will give you a good education and a lot to practice and think about. and if you decide to never count, $25 isn't much to spend
