$6 Speed flopped 2 pr with all diamond flop. What to bet??

[chekraze]

What's my best line here to price out any diamond draw? Better to push at this buy-in level or play the flop easy and if no diamond hits the turn then bet hard before river? Also, I know min-raise is unpopular and in my position and being level 2 is this a limping hand to anyone?
