Here is a build that should give you decent damage output as a second line fighter. You will spring attack in for a single good hit per round and stay out of full attack range. This build also includes good int and max ranks in disable device and search to ensure good trap handling ability. The hide and move silently scores are similarly strong.

Advancement:
I would continue to build with rogue levels, maybe a PRC later, but always be minful of your skill ranks in hide, move silently, search, listen, spot, open locks, and disable device. Pump your dex as high as you can. Get boots of striding and springing or speed as soon as you can to extend your movement. This build's combat maneuver is pretty plain, spring attack for one big hit from the flank of your target. Soon your tumble mod will be so good that you can tumble at full speed on a 2+ during your spring attack to avoid AOOs from every enemy, not just your target. You will put out respectable damage in that capacity without consuming much in the way of healing resources from your party. You will also maintain very solid trap finding and negotiation abilities.
