Battle of the blinds with JTo

[SCfuji]

I have a few weaknesses that I would like to focus on eliminating from the 6 max games(I have more, but I want to tackle them one or two at a time). The first is when everybody folds to me in the small blind and I have a decent holding as I did in this hand:

BB has a VPIP of 40 and PFR of 0.xx after 50 or so hands. His Flop Aggr is 0.80, Turn Aggr is 1.00, and River Aggr is 2.30.

Preflop: Hero is SB with T[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/spade.gif[/img].
<font color="#666666">4 folds</font>, Hero completes, BB checks.

Question #1: Raise Preflop?

Flop: (2 SB) J[img]/images/graemlins/club.gif[/img], 7[img]/images/graemlins/spade.gif[/img], 3[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets</font>, <font color="#CC3333">BB raises</font>, <font color="#CC3333">Hero 3-bets</font>, <font color="#CC3333">BB caps</font>, Hero calls.

Question 2: With this villain's flop aggression was I wrong to cap this on the flop? Should I have waited for the big bet street to unearth the 'strength' of my hand?

Turn: (5 BB) T[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">BB bets</font>, <font color="#CC3333">Hero raises</font>, <font color="#CC3333">BB 3-bets</font>, <font color="#CC3333">Hero caps</font>, BB calls.

Question #3: Alright! I have top 2-pair. I am ahead of most hands that the villain could have been raising with on the flop.

River: (13 BB) A[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets</font>, BB raises $4 (All-In), Hero calls.

Question 4: This river card somewhat sucks, but I still felt like I had the best and a bet is in order and I am definitely not folding to his all-in raise.

Final Pot: 17 BB

Notes: I basically thought this chum was spewing chips on the turn as his stack was dwindling down to the felt, so I thought I would tag along for the ride. I'm sure people will have different actions to suggest on different streets and I would appreciate any insight.

Thanks,
