B&M 1/2 Noob PF question

[ChuckyB]

Last night was my third ever B&M 1/2 NL game. I bought in for $100 until I figured things out.

10-handed. My image, to the half the table that's paying attention, is tight.

I was dealt KQ in EP about 5 times. Once suited. Most times I had about $100 behind with everyone covering. Once I had about $320 and was covered in 4 spots.

Table was loose and generally passive at this point. 5-10 to the flop (6 is most common). A player 4 to my left had $500+ and would occasionally use it to push people around. He thought AJo was good for a raise after 6 limpers in one hand. Lower raising standards than most. He was moderately readable.

I think I played KQ every time, knowing I have to be super-careful if I hit top pair. Twice I raised 3BB+1 (or so). The other three I limped. One of my limps was called in 4 spots, then the SB raised to $6.

In short, I have no idea what to do with KQ (except be super-careful if I get into the flop). Any thoughts you can share about it in low-limit game would be very helpful.
