Big time fundamental errors (your action?)

[MediaPA]

I was chasing my money after losing $1k on TPTK 9 high board to JJ. I had every reason to believe that I was dead, but I got locked onto the hand.

Anyway, here are 2 hands from later in the session. I'd be interested in what you'd do in my spot. I have no reads. My apologies if these are fundamental situations, but I tend to play outside my BR (the stakes say they belong here).

BB ($2075)
UTG ($4400)
Button ($2333)
Hero ($2605)

Preflop: Hero is SB with A[img]/images/graemlins/diamond.gif[/img], K[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">Button raises to $65</font>, Hero calls $55, <font color="#666666">1 fold</font>.

Flop: ($155) 5[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets $155</font>. Button raises to $620.

Your action?


BB ($2473)
UTG ($511)
MP ($4312)
Button ($4213)
Hero ($3314)

Preflop: Hero is SB with J[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/club.gif[/img].
Hero completes, <font color="#666666">1 fold</font>, Button calls $25, <font color="#CC3333">Hero raises to $125</font>, BB calls $100, UTG calls $125, Button calls $100.

Flop: ($500) 5[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/diamond.gif[/img], 9[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>

Your action?

I'll post what I did, and my logic behind it later. Again sorry if these are 'autopilot' plays for the majority of people.
