I want my deck to overhang my support posts. I would like a two foot overhang. What size joists should I use. Also, would 18" on center be close enough for the joists?

2' is the maximum. 2x6 joists 16" on center. Many put them 14" on center. It takes the bounce out.

A 2' cantalever is the maximum. Joist spacing depends on what you are using for deck boards. If you are using 5/4 decking, space the joists at 16" O.C. With 2X6 decking, 18" is fine. Could stretch that to 20", but I wouldn't unless it were necessary to reduce waste.

It takes the bounce out of the overhang or the main part of the deck? Would 2x8 joists serve the same purpose? Thanks for your input.

Keeping your joist cantilever at 24" or less will keep 'the bounce' out of the area that is cantilevered. Keeping the joists at 16" O.C. or less will take 'the bounce' out of the deck boards. You can doo it all with 2X6 joists and be just fine. Going to 2X8 joists wouldn't change any of that, but it would allow you to spread the girders (4X6 or whatever)that are supporting those joists about another foot or so apart.
