1-2 AKs hand: two questionable flop decisions?

[Robk]

The first three players limped and I made it $8 with AK [img]/images/graemlins/heart.gif[/img]. Two of the three limpers called and everyone else folded. I started the hand with $95, the middle player had $83 and the first player had us covered. The flop was K [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/spade.gif[/img], $28 or so in the pot. The first limper checked and the second limper bet $10. I made it $40, and the first limper called my raise. The initial bettor then made it $75, putting him all-in and I folded. Should I have done anything different?
