I sleeved my cards just to keep 'em safe. You don't really need to dry erase anything if you don't want to.
The tokens are easily glued to dice. I just primed some square edged dice black, super glued them on and then sharpied the edges to make them blend.
You've got 5 positive states and 6 negative ones... so they go quite nicely on dice so you don't have to fiddle so much.
I use
D20's for Damage as they're the easiest way to track life points and it's rare for a model to have more than 20.
Hope that helps!
