2×6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. … Most decking is not strong enough to support longer spans than 16″.

Should you use 4×4 or 6×6 deck posts?
4×4 post will be fine. I have built many decks for new homes with them. 6×6 is more sturdy of course and will not twist as easy, but for structure purposes, 4×4 will be fine. I would just not go more then 10′ apart with them.
