PokerStars 25NL (9 handed)

villian is very loose. I am fairly confident he will bet if checked to, but I'm wondering whether a weak lead might even get him to raise.

CO ($9.15)
Button ($16.30)
SB ($26.15)
BB ($33.35)
UTG ($17.85)
UTG+1 ($24.15)
Staresy ($25.60)
MP2 ($39.65)
MP3 ($16.90)

Preflop: Staresy is MP1 with 8 8
2 folds, Staresy calls $0.25, MP2 raises to $1.25, 1 fold, CO calls $1.25, Button calls $1.25, 2 folds, Staresy calls $1.

Flop: ($5.35) 8 5 7
(4 players)
Staresy ....

(a) leads?
(b) check-raises?
(c) check-calls?
