K/9o in CO, dead SB — steal?

[marchron]

Button is 44/10 but passive post-flop.
The player in the SB position just left, so there was none.
BB is 44/12 but more aggressive on later streets.

I consider my specific reads on both of them to be fairly strong.

I think I steal too many blinds. Is this a case where I should have backed off? Should the lack of a small blind influence my decision either way?

Advice on all streets, please.

Preflop: <font color="green">marchron</font> is CO with K[img]/images/graemlins/heart.gif[/img], 9[img]/images/graemlins/spade.gif[/img]
<font color="#666666">5 folds</font>, <font color="green">marchron raises</font> . . .

Good move?

Flop: (4 SB) 6[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/club.gif[/img], 3[img]/images/graemlins/club.gif[/img]
<font color="#CC3333">BB bets</font>, <font color="green">marchron . . .</font>

Now what? He clearly thinks I have nothing and is being his LAGgy self. I have TP2K and I doubt very much he has anything save maybe two overs. Do I let him know I hit this flop, or dare I continue to let him bet into me?
