I've made some player and GM aids that have helped me quite a bit.
Here's a link to the thread where you can download them:

I've got a crib-sheet for common rules that fits in a GM screen or can be printed out and just used for reference. I've got sheets where you can write up all the GMCs you plan to use in a game and have them all in one place. There's also vehicle sheets where you can track the stats of vehicles AND have quick-reference to the vehicle chase and combat rules.
I've also made full-color playmats for each of the Junctures, with common rules references on them as well.
