Normally with pocket 7's or lower i limp in and with pocket 8's or higher I bet3-5x blinds, knowing that i'll most likely be dealing with overcards.

Let's say I have 88 and raised 5x blinds and 2 others are in. The flop is 7 4 2 Rainbow. I'm in last position and the 2 people before me check. if each has a bigger chip stack than me, what do u do? Do you attempt to take the pot right there? or do you wait till the turn and see if another over card comes up? or what?
