Get cards, start playing with someone who already knows their stuff. I've found this to be an invaluable way of picking up experience, especially with PTCG.
Being creative with deck ideas may also be a very good way to learn some of the nuances of the game, the threads I began on Politoed/Celebi-EX springing to mind.
And on that note, asking awkward questions. There is no better source of information for this game than the people who play frequently and/or make the rules.
The hardest thing to learn? Timing the usage of certain cards to get the most out of them, and by extension keeping a variety of cards in the deck without going overboard so I always have what i need. knowledge of the nuances of these things come from another great source, experience. Keep building and playing and you'll get to understanding it all soon enough.
I know none of these things are particularly revolutionary concepts, but if it ain't broke don't fix it.
Good luck with the project
