Make sure you take the colour out, or its obvious what you did!

Yeah raise more pre, probably like $4, the general rule is 3 or 4 xBB + 1BB for every limper. Don't bet so weak on the flop either. Make it 7 or 8. As for the flop play meh, without reads/stats its tricky - but it looked like a set mine, limp call UTG 66? Otherwise if he's a bit of a donkey could be a range of FD/TP/Straight draws which you are ahead of. With him being short I probably just push anyway.
