Upgrade my mode 11 TP 22-250

Hey guys I just bought a savage model 11 trophy predator and I was researching different stuff about it and happened to stumble across this forum. I had no idea you could buy sweet aftermarket stocks, bolts, barrels, muzzle brakes, suppressors, and stuff like that until I saw what you guys have done. What do I need to do to get a Boyd's featherweight thumb hole or a pro varmint stock onto my gun. It has the detachable magazine along with bottom bolt release. Not sure of that would make a difference or not.
Would love to buy a tactical bolt but not sure where to find one. Any help guys would be much appreciated. Oh ya and how do I thread the end of my barrel without fackin it all up?
