TPBK - How Are My Lines?

I'm Still trying to apply the fundamentals and I want to see how I'm doing. Please critique all streets:

Table overall is 21/9 over 80 hands. Way too tight for my normal taste but I was up 15 BB and playing well overall.

UTG+1 is 22/10/2.0 over 50 hands
MP3 is on his first orbit.

Preflop: Hero is UTG with J[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/heart.gif[/img]. MP3 posts a blind of $0.50.
<font color="#CC3333">Hero raises</font>, <font color="#CC3333">UTG+1 3-bets</font>, <font color="#666666">2 folds</font>, MP3 (poster) calls, <font color="#666666">2 folds</font>, SB calls, BB calls, Hero calls.

<font color="green"> I would normally only call AJo UTG but I made a nOOb mistake and thought I was in MP so I bet not seeing any raise in front. I called the 3-bet since I had already committed the first bet. </font>

Flop: (15 SB) 2[img]/images/graemlins/diamond.gif[/img], 5[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, BB checks, <font color="#CC3333">Hero bets</font>, <font color="#CC3333">UTG+1 raises</font>, <font color="#CC3333">MP3 3-bets</font>, SB calls, BB calls, Hero calls, UTG+1 calls.


<font color="green"> I flop TPB(est)K and figure I’ve got the advantage now so I led because I’m pretty sure UTG+1 will re-raise. I didn’t expect the 3-bet from MP3 so I only call thinking he must have a high PP that he was slowplaying, maybe even the other 2 J’s. </font>

Turn: (15 BB) 7[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, BB checks, Hero checks, <font color="#CC3333">UTG+1 bets</font>, <font color="#CC3333">MP3 raises</font>, SB calls, BB folds, Hero calls, UTG+1 folds.

<font color="green"> I see the possible [img]/images/graemlins/diamond.gif[/img] and [img]/images/graemlins/spade.gif[/img] flush draws on the board so I am prepared to c/c here given I’m OOP but figuring since the pot is huge I still have odds to call. </font>

River: (22 BB) J[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, <font color="#CC3333">Hero bets</font>, <font color="#CC3333">MP3 raises</font>, SB folds, <font color="#CC3333">Hero 3-bets</font>, <font color="#CC3333">MP3 caps</font>, Hero calls.

<font color="green"> The 3rd J falls and now I know that MP3 doesn’t have but 1 J at most and I’ve got the A kicker. I fire way til I call the cap. </font>

Final Pot: 30 BB

Including the nOObish mis-raise pre-flop, I didn’t feel good playing this one. Was I too weak on the flop and turn? Did I misread something? One flaw I know for sure was that I wasn't paying any attention to the overcallers. Thanks!
