I want to set up a switch barrel gun for a REM700 LA and Surgeon

I have savages that i have changed the barrels on. But never anything else. My 700 action is with kirby right now so i would just have to get him to chamber another barrel and pin the recoil lug to the action right . The surgeon action would just need the barrel chamber for it. Whats the best action wrench and barrel vise to get for these action so i dont scratch the paint job when i switch barrels.
rem will be 375 rum and 270AM surgeon will be 338whisper and 308.
