Hey sharks among men,

While progressing and learning much from the videos and advice on forums here, I've noticed that with new good habits come new bad habits – ways while learning we overstep and sometimes completely step off cliffs, into mouths with teeth.

I wonder if I am jamming too much preflop in these spots in an effort to increase aggression and maintain higher M.  Here are two spots.

1)

First hand was two days ago I believe a 5$ turbo knockout. We are at around midgame but things will start heating up soon.  The villain, ARMYMIRET, after just 28 hands played 43/28/0, stealing 25, had just nicely ninjaed himself back from 960 chips about ten hands ago.  Four hands ago, at 150/300, he had 2700 in chips in the BB, as did the low stacked SB, who tried to min open steal BSB, and ARMYMIRET decided to flat defend his BB with 9T.  Flop was XX9, the BB shoved with KJ and ARMY easy called to double up and take out the SB player. Then this:

sandyhookKYguy (CO): BB = 7.8, t3136
MMAjunkieX (BTN): BB = 11.3, t4510
latoya22 (SB): BB = 3.6, t1457
Hero (BB): BB = 11.4, t4541
gunnernme (UTG): BB = 6.6, t2623
sf49ers831 (UTG+1): BB = 10.1, t4040
ARMYMIRET (MP): BB = 9.3, t3733

Pre Flop: (t880) Hero is BB with 6 Q
2 folds, ARMYMIRET calls t400, 2 folds, latoya22 calls t200, action on Hero

I decided that I hadn't made a move in long enough, and wanted to be aggressive.  Maybe I ranged him improperly .. but not really because it's not like I didn't believe he could be limping to induce. But I thought enough of the time he was going to be limping somthing he could fold while he gets the feel for the table with a reasonable stack.  In any case I wanted to pick up some chips.

Hero raises to t4501 all in, ARMYMIRET calls t3293 all in

Is it ok to do this?  Did I do this too early in the MTT?

2)

Second hand was in a 2$ rebuy turbo MTT, this time about halfway between the addon period and the bubble.  The villain is NRewolf, after 27 hands playing 22/16/12.5, steal 33, fold to steal 50, resteal 0 but I know the sample is small.

Pre Flop: (t1100) Hero is SB with 8 J
5 folds, action on Hero.

I decided to steal his blinds.  I'm ok going that far, right?  I think so, but then I probably did it too mindlessly.

Hero raises to t8400 all in, NRewolf3 calls t7900

Should I have bet something like 2.5x or 3x if I decide to steal?  I wonder if I was too large to shove?  I know I wasn't large at all.  But too large nonetheless for this?  If I bet 2.5x, I could fold to a reshove and if he calls I have 15BB to work with.

With this stack is a shove too spewy?

Thank you very kindly for your inputs.
