How Should I Play This Hand

[oldmangrimis]

I am playing in a $1-$2 NL holdem max buy in is $200 at a live casino. I have been playing tight for 2 hours and the table is playing loose before the flop and tight and calling alot after the flop, but the player are over valuing the top pairs. I have K9o and have $100 and 7 player limp in . Flop is Kh 9s 5d. The pot has $15 I have top two and bet the pot on player calls, turn is Tc and I bet $30 and the other player go all in for $75 and i call. Now just knoing the info is the any play that i could have played to play it better.
