Do you have any regular Heroscape figures and cards, too? I would suggest playing by the actual rules with actual figures first. Then when you introduce fan made content, like LotR stuff, the game will make more sense to you. You'll understand how the game is supposed to play and how your custom figures might differ.
The Heroscape system can handle all sorts of variation, but I think you'll be more comfortable with a strong base understanding of the system first.
