It'll make a little more sense when we start previewing miniatures next Friday, but suffice to say for now that the pledges are pretty open-ended in terms of what you want to include. Apart from the most basic, which is just a rulebook, pledges in the $100-750 range are structured as rulebook + $X of your choice of other goods. The higher the pledge, the greater the discount. We also have a few 'uber' pledges with unique items that are set up a little differently.
Oh, and there is a quick reference product in the works, but it wouldn't really be practical to produce as cards.
