calling in BB with suited queens

[bad beetz]

You have QcXc with X <= 8. you are in the big blind.

What odds/texture/whatever do you need to call a raise?

Come on bad beetz, you know the answer to this one. As for type of game, a loose passive game is better because post-flop you want the proper odds to draw to a flush.

As for number of people in the hand, you want more than a few. Without knowing the exact odds of flopping a flush draw/trips/queens up, I'd say you want at least 4 other people in the hand (probably more).
