30/60 5 handed 99 vs 2 lags

[Seether]

Both of my opponents are pretty LAG, it was a couple days ago but their pf stats are about 45/20ish + or - a couple points in both. What are the thoughts of my play up to the river? I felt that betting the flop against them would do nothing as they would call it with just about any 2 cards and Id still have no idea where I was at going into the more expensive streets.
And what should my river decision be?
