Theory type questions about preflop reraising and calling reraises

[Don Key E37]

Ok I'm going to try and not make this to long and get my questions out as best as I can. A bit of background I am just coming out of my worst run ever (I'm sure some of you saw some whining in the cheese thread and I'm sorry) and looking to learn from it and hopefully have a better run at 200NL in a bit after some rebuilding.

One of the things that initially threw me off my game when I moved up to 200NL was the increase in preflop 3 betting. 3 betting preflop light was something that was not previously part of my game at all, and I'm trying to lighten up a bit now. It used to be if I reraised preflop I either had 10s + or AK. I look at some peoples pokertracker screen shots and can't understand how someone could be 21/19 (I think I saw dbitel with similar numbers). I've been running like 21/13 and I never open limp but I think a lot of the smaller preflop raising numbers comes from calling with small pairs or like J 10 suited on the button or CO. Like in a 100NL game UTG raises to $4 I'm calling with 33 on the button here. Would some of you reraise here? What if it was J 10 suited? When I look at a pokertracker session and see I played 22/11 I feel like I'm still making fundamental mistakes preflop. I know one leak is just completing from the sb to often in limped pots and I'm working on that, but it still seems if there are 3 limpers and I have 89o its worth the half bet to see the flop.

Question 2 $100 dollar stacks at 100NL I'm utg and open to $3.5 with 55, folded to sb who makes it $13. I've been calling here, mostly for set value although I do try and take the pot if the opportunity comes up ( I usually get check raised all in on the turn after 2 checks). Is this a mistake? I used to think it was fine to call just for set value really because it's 10 to me to try and win his 100. The problem is with people reraising lighter now is that where before I was very likely to stack him when I hit vs his big pair, now he may not have anything and get away cheaply making me fold when he has nothing often, and him getting away with a good amount of his stack when I do hit. Also if it is correct to call here then Shouldn't I be reraising more when the situations are reversed?

Basically I've noticed that the opponents that give me the most trouble are the ones that are laggy players on my left who constantly float my flop bets, and people that relentlessly reraise me preflop. Also that small stakes players tend to play much worse than they normally would in reraised pots. So since I find it more difficult to play against these things I should start doing it more myself. You know just learn from your tougher opponents. But I also remember a thread a bit ago where orange and a higher stakes player came to the conclusion that they thought it was better to just call on the button with 88 rather than reraise most of the time. Reraising AJ still seems like spew to me so I guess I'm lost as to where I should be reraising more. One last question is there a way to see stats from only preflop reraised pots in pokertracker?

I've read threads on some of this previously and am going to go back and search for some others, but I would definetly appreciate any responses/help from veteran posters or anyone who thinks they can help. Thanks again hope this wasn't to long and rambling.
