Well, nearly 4k hands racked up at 3/6 HE at empire now and I'm, unfortunately, also pushing 400 down

I feel i'm playing reasonably well and being a bit unlucky, but equally I feel i'm playing far from perfectly and missing a few bets. Thing is, multitabling as much as I do, I don't feel I'm liable to play THAT much better than I am currently, so I'd appreciate any input on this. Here's some of my numbers and concerns:
VPIP 13.7% - don't think this'll ever get much higher. If anything I feel I am playing too many hands, perhaps my only issue is not defending my blind often enough to steals
Question - I raise PF with a hand like AQo and someone 3-bets.... Decent enough to call and then take one off if I miss the flop? I'm routinely making plays like this against average players and wonder if it's a leak. Same with the likes of 88, 99, AJs etc in MP and LP.
VPIP SB 18% - so I play 5% more hands. Probably I call too much from SB, given it's the worst position. is 5% more ok, given it's 2/3 of a SB to call? Or should I be just as tight as the other positions? I don't feel i'm leaking much here.
Question - if it's folded to me in the SB i routinely raise hands like A4o. Sometimes I win the BB outright, sometimes he calls. I usually bet the flop then, regardless. I have won one or two nice pots by just betting hard in this spot although I feel i'm not always picking my spots. I won quite a big pot with A3o when I made a steal raise from LP, he popped back with the blind, I capped, raised him on the flop, then bet the turn when he checked- he folded and I won unimproved! I don't make a habit of that though, perhaps not even enough. If it's folded to me in the last two seats, or the SB, is it OK to raise just about any half decent holding (Axo, Axs, Kxs, low pairs, suited connectors etc etc)?
Fold SB to steal 88%
Fold BB to steal 66%
Question - I fold 66% of BBs that are raised? IS that what this means? If so, should I be seeing flops with more than a third of the hands, given i'll be getting like 3-1, 4-1 odds minimum? What hands should I defend with

Att. to steal blinds 24% - too low?
Won $ when saw flop - 33%; given it's rare for more than 3 or 4 players to see a flop, is this a little low? Evidence of a bad run, or perhaps folding some winners??? I don't feel like I'm folding many winners, though perhaps i am laying down weak hands sometimes when i dont try to steal often enough... thought I feel I AM stealing quite often and usually get caught! Maybe that's just my mental image and perhaps i am playing too tight-passive...
Went to SD% - 26% - this seems ludicrously low. Again, just a bad run or a sign of something wrong? What numbers do you guys have?
Won $ at SD% - 60% - this seems about right - given my low WTSD and W$WSF numbers, does this mean i'm just running bad?
PFR% - 6.6% - I'm not likely to be raising any more hands. Already I am sometimes making raises I feel uncomfortable with, Like AJs in most seats and pairs like 88 and 99 etc. Maybe I could raise a few more things in LP, like A9o, ATo etc first to act?
BB/100 - minus 1.58
Hands:
AA - playing this fine. 85% winning so far, 2.5BB/hand
KK - 1.6 BB/hand, won $ at showdown only 63% though?
QQ - 0.6BB/hand ugh. 50% W$SD
JJ - 0.33 BB /hand. 75% W$SD. Small sample but maybe folding too often?
TT - -0.17BB/hand (Losing) 40% W$SD
AKo - 0.17BB/hand 50%W$SD
AKs - 0.8BB/hand 50%W$SD
AQs - 0.38BB/hand 75%W$SD
AQo - 0.23BB/hand 50%W$SD
AJs and AJo are both losers/break even, AT is a loser for me (ATs a small winner, ATo a slightly larger loser, -0.53BB/hand)
KQs and KQo are both around break even, I have a 33% and 25% PFR% respectively. OK?
Pairs below TT ar 0.06BB/100. VPIP for these combined is 60%. Is this too high, or about right?
Aggression:
Total post-flop: 2.80
Flop: 3.5
Turn: 3.4
River: 2.1
Too passive on river? I've maybe missed a bet or two here, but then also I seem to be being run down a LOT at the moment when I hold a middle pair or something, bet all the way, just for some passive goon to turn over a strong top-pair.
Anyway, food for thought! I must admit i'm a bit put off by limit again, when I used to play about 2 years it seemed to me i won a lot more, I think the games were a lot easier back then, but I WOULD like to be a decent winner in the medium term, and being that I'm only 400 down i guess that's possible, but I'd have liked to have been doing better after 4k hands really.
Thoughts from you limit-ites, please!
