Law / After marriage do I have to file for Poland residency? [6]

I'll be getting married to a Polish man, in Poland, very soon.
Once we're married, will there be other things that need to be done? Such as filing to be able to work, and do I have to file for residency, or does being married mean I don't have to do this? I'm here in Poland on the 90 day, where I don't need a visa. The time from that will be up soon though.
