What a lucky crossroad you see yourself at.
I'm taking a break, so I'm able to give my opinions...
I would suggest playing more live tournaments. Entries ranging from $50-$500 seem good for you, with an occasional $1000 entry tournament thrown in the mix. (Borgata / Taj event in the near future, etc.) Maybe you'll do well (which will lead you to more crossroads!) or maybe you won't. Either way, you'll be able to sufficiently gauge how you do in the "live tournament" scene, and, more important, see how you like this "genre" of poker.
While doing that, I would couple $6000 of your winnings with your already-existing bankroll and being playing $10/20 full. Get used to the bets and "levels" of players playing full, and then move to 6-max. Back in your "preferred game," see whether you can grind your way up to the next level.
As far as the rest of your winnings ... Pay Per Post: retroactive from January 1st.
