Yes, the Bekaa Valley is now terrorist central in Lebanon. It will be interesting to see whether Assad will withdraw his troops from there and leave his proteges without Syrian protection. This is a serious sticking point for his ally Iran as well, since these are the mad ayatollahs' clients too.
Hezboallah is going to stay and make things lousy for the rest of Lebannon. Arms and dope will continue to be smuggled (that is how things are paid for in this neighborhood). Lebannon is going to think we abandoned it like with did the Shia at the end of Gulf War 1. Don't Syria may or may not move Sadaams WMD into Syria. I doubt we will attack them directly either in force or in punitive raids. We have our hands full in Iraq right now.
