10/22 upgrade questions

[DFBrews]

Since building an AR is out of the gun budget for a while I am giving my old 10/22 a tune up. I sand blasted and clear coated the receiver and trigger assembly, looks really good. going to re finish the stock from blonde to a red chestnut as well.
I ordered the Volquartsen target hammer along with the extractor plunger that flew out during assembly of the bolt after I jeweled it and safety spring and plunger that where lost during removal... that is one hell of a little spring.
If I polish up the sear and disconnector with the new hammer will my trigger pull be to light to be safe?
I plan on putting a 18" bull barrel in stainless on it. free floating so I am pretty sure I need to bed the barrel and action, should I pillar the take down screw as well as the action or just one or the other? I am going to bed the barrel to the balance point.
also I am going to add a over travel adjustment screw but don't know whether or not to put the set screw on the trigger or in the trigger guard ( it is a 1984 rifle so the guard is Aluminum.) and I have little tiny taps

Basically right now I know enough about accurizing them to be dangerous but not enough to be effective.

Any help would be amazing.
