Foolish laydown

[dethgrind]

So I made what I think was a huge mistake a couple days ago. I'll summarize what is below: 9 players remain with blinds at lvl 2, I limp in EP with A[img]/images/graemlins/diamond.gif[/img]J[img]/images/graemlins/spade.gif[/img], 2 others limp, SB completes, BB checks. 5-way flop with 150 in the pot. Flop comes J[img]/images/graemlins/diamond.gif[/img] 3[img]/images/graemlins/heart.gif[/img] 2[img]/images/graemlins/diamond.gif[/img]. Blinds check to me, I bet the pot, all call except the BB. 4-way, pot is 750, turn comes 5[img]/images/graemlins/heart.gif[/img], SB checks, I have 950 left, bet 350, get raised to 700, one player folds, SB calls all-in, I fold. River comes 8[img]/images/graemlins/spade.gif[/img], raiser shows A[img]/images/graemlins/heart.gif[/img]8[img]/images/graemlins/heart.gif[/img], SB shows 4[img]/images/graemlins/spade.gif[/img] 4[img]/images/graemlins/diamond.gif[/img], raiser takes it down with a pair of eights.

The flop bet seems pretty standard, but perhaps I should have overbet it a bet. Do you agree with the turn bet? Clearly in this case the fold was a terrible mistake, but in general is it so bad? Should I have bet more, or possible moved in? If the bet was correct, should I have moved in after getting raised? I'd appreciate any comments that don't make fun of me [img]/images/graemlins/smile.gif[/img]
