I wouldn't get too caught up in CRF vs push feed, especially for a 6.5x47. I have both CRF and push feed, they both work.
For barrel, a finish length of 24-26" is popular. 1:7.5" or 1:8" twist. Heavy Palma, m24/m40 profile or MTU. Go to bugholes.com and get a barrel there, lots of good options in stock. Krieger, Bartlein, Brux, Rock Creek, etc.
For action my preference would be ARC Mausingfield, Impact or Lone Peak. I would avoid Stiller - they feel pretty rough. Some people love the TL3's, but I'm not a fan of how they feel, really sloppy bolt and easy to bind - but that's just my personal preference. They do work though. Not sold on Defiance for really dusty conditions. Ive been bitten in the ass by Defiances tight tolerances in really dusty conditions (as have some of my other shooting buddies running Defiances in PRS matches - though others swear by them).
It's interesting to see the action preference based on geographical location. The actions that are popular in areas will differ based on who the local PRS shooters are sponsored by, who the local manufacturers are, and what the popular gunsmiths push. Take everyone's opinion with a grain of salt, and try to figure out why they are pushing a particular action, rather than taking it for face value.
The rest of the components you need to select based on your personal preference. Triggers, stocks/chassis, etc. are a personal preference based on your body type/shooting style/etc.
