In addition to the excellent questions here about revenue and runway, if equity is a significant part of your comp (read: if you could make more money elsewhere and you're not taking the pay hit because it's the job of your dreams) there are more things you need to know. I'd want to know total investment, the liquidation preference and if the preferred stock is participating. This will give you a good idea of the exit required for your stock to actually be worth anything. Knowing the makeup of the board is useful too, i.e. how many are VCs compared to common holders.
