The only skills you have to have as a trapmonkey are Search & Disable; Spot is helpful (esp. for first-timers who don't know where all the traps are), but not necessary; likewise it's good to have at least half-ranks in Open Lock. But don't neglect UMD either!
Nobody ever recommends the trap-skill-boosting feats because they're unnecessary; DPS feats are usually far more useful. You'll rely on items & buffs to boost your skills, not feats or base stats. Consult this for more info.
Here's a build which will do what you want without sacrificing nearly as much DPS as your build. 23 ranks in Search, Disable, UMD; 17 ranks in Spot; 8 ranks in Open Lock. [Taking a +2 INT tome at lvl 7 would let you bump up Spot and/or OL higher.] Could dump-stat DEX for more CON: lower AC (irrelevant) & Reflex saves for higher HPs and slightly longer Rage. Lvl 18 feat is up for debate, too.
