marriage questions

I have a few questions, bare with me if they sound stupid, I apologize if they do...

1. If I'm a stay at home mom, does this affect taxes in a bad way or at all?

2. Are there any cons to getting married that will change anything in a bad way? Money wise, bills, taxes, etc?

3. How long does it take to recieve a marriage license, what all do we need to get one & how long do you have to get married after you get it?

4. Are there any cons to getting married/pros?

Sorry, I don't have anyone to talk to about this. Google doesn't really help, also, we would just elope more than likely just court house wedding.
