NL100 limping shortstacked with AJo getting tPwk

[oberon]

I just looked through old hands and wasn't sure how to play this hand, so I am asking the whise 2p2 members for some good advise [img]/images/graemlins/smile.gif[/img]
Normaly NL100 is too high for my level, but I gave it a try some time ago, playing shortstacked.

Party Poker Texas Holdem NoLimit100 (blinds $0.50/$1.00)
8 persons playing
Hero has A[img]/images/graemlins/diamond.gif[/img]J[img]/images/graemlins/spade.gif[/img]

Preflop:
UTG fold
m3 no stats ($137.70) limps in with $1.00
m2; m1; cutoff and button all fold
sb Hero ($ 19.00) limps in with $0.50
bb 9/7/0.8(86) ($ 39.10) checks

I thought AJo isn't that good as shortstack so I just limped. Is it good enough to raise aggressivly here?

Flop: ($3.00) 3 persons playing A[img]/images/graemlins/spade.gif[/img]Q[img]/images/graemlins/heart.gif[/img]5[img]/images/graemlins/club.gif[/img]
I got topPair with a weak kicker,
with a single oponent as bb with a very low Aggresion-factor like 0.8 I would overbet the pot, but here I have a unknown bigstack in m3-Position. Is it a good Idea to play tPwk against two players? So I did a kind of c-bet

sb ($ 18.00) bets $2.00
bb ($ 38.10) folds
m3 ($136.70) calls $2.00

I'm slowly getting pot-comitted...

Turn: ($7.00) 2 players A[img]/images/graemlins/spade.gif[/img]Q[img]/images/graemlins/heart.gif[/img]J[img]/images/graemlins/heart.gif[/img]5[img]/images/graemlins/club.gif[/img]
So I got double-Pair.
What would you do here?
