I think the questions you've outlined are usually what anyone should be worried about, except maybe the dog friendly one :-) Also, it would be good if you can do some research in the the main business model for the company. How familiar are they with their target market, what is their target market? and stuff like that. I've found quite a lot of startups are clueless about that. Finding a year down the line that the equity(over cash) is worthless... is certainly not a good feeling. I've been there personally so i know. If you're taking equity, get something written on the equity agreement and this is a MUST!
