Should I take this job?

John Wilkins [who I was fortunate to do a postdoc with] has this useful one page guide on Accepting/Rejecting a Job Offer.

I would add that once you get one offer you should write to other places you have applied to and tell them. You should either tell them you are no longer interested or that you are still interested but under a time constraint to decide on your offer. This may stimulate them to proceed faster with a decision about your application.

But, do NOT collect offers just for the sake of collecting them.
