I haven't met up with my group in a while, but when we do, I usually use a special laminated grid from Steel Sqwire for combat, and a dry-erase whiteboard for keeping track of initiative, status effects, VP/WP (I use SWD20 too.) and other such things. For miniatures, I usually use Legos, coins, rocks, and the occasional WH40k figurine. I'm eventually going to make little cardboard chits for each of my regular players to use for their characters.
