Well as Ferguson claims there is no better way to learn the game by then playing. Here it looks like you made a few plays at some pots that were just not the correct play at the time. However it looks like youve already learned from those mistakes; these situations are going to happen all the time. In my opinion you should just keep playing so long as you knwo that youre going to be at your optimal game. As for trying to get out of a tight spot with added bets in low-med limit youre unlikely to win a pot with a bet/raise on the turn or river assuming the other player is not extremely tight which is unlikely in a 6 max.
