Heh, I was just looking this up last night myself. Looking forward to what others might suggest. Here is the basic info I was able to scrounge from the intergoogle. Torque on the action screws was suggested anywhere from 35-52 in/lbs. I will stay closer to 35-40.
Tikka action bolts - 35-40 in/lbs
Talley Rings:
base to receiver:20-25in/lbs
ring halves:15-20in/lbs
Also, I am trying to go back and find this one video where a guy used two different torque settings for each of the action bolts as he said "his rifle like it better that way". I guess if you have the time and money for ammo you can experiment with all sorts of variables. Personally I figure the gun will out-shoot me with pretty much any torque settings so I'm not too worried about finding the absolute perfect setting.
