I've been working on a project gun for almost a year. I had originally contacted Dane about building it, but money (why is it always money?) became a problem, so I've been working on it, paycheck to paycheck, myself.
Polishing the disconnector track is easy, and allows the gun to cycle smoother. Likewise, polishing the inside of the mainspring housing makes for smoother cocking and cycling. When you install the new trigger, be sure to polish the ways in the frame in which the trigger rides. All of that stuff can be done without having to do any refinishing. I've had good results with Marvel oversize hammer and sear pins. You need the proper reamers to use them, but they ensure there's no wobble in the hammer and sear.
