wire size
I was told I need to run 14-2 for this and 12-2 for that. My question is can I run the bigger wire thru out the new addition? Do I have to get bigger breakers? Is it cheaper or more expenive to get one size or both sizes of wire?

You may run the larger wire throughout. It is slightly higher $$$, but not much. There are benifits from running larger wire esspecially regarding reduction of volt drop. You may run #12 awg wire and connect it to either a 15 or 20A breaker. Many folks do it that way as a matter of practice.
