Q9s in BB...Big flop??

[RIDGE45]

No solid read really. Villian has been in a decent amount of hands, so his range is pretty broad. Seems to be pretty solid post-flop.
Minraise from button really confused me...I took it as a weak steal attempt, or an attempt to get action on a big hand (1010-AA, AKs, AK).

My Questions with this hand (main issue is with flop):

1. Call minraise preflop from BB?
2. Was going for a C/R on the flop. Is this line correct? And if so, how much to checkraise if Villian comes out with a 1/2-3/4 of the pot bet?
3. Should I just lead out on the flop? If so, what if I get reraised?

Comments on all streets appreciated.
