Bedding isn't overly difficult, just remember to follow the rules about tape and release agents. The last thing you want is the barreled action epoxied into the stock. I used several light coats of Johnsons Paste Wax on mine and all but one came right out. The one came out, I just had forgotten to coat the longer replacement action screws and it sure gave me a scare for sure. A good smack with a rubber hammer released them real quick.
If you have a dremmel tool it makes cleaning out around the mag well and action pretty quick and easy, just go slow and remove it a little at a time.
Trigger's, while I have done a couple myself, I have had all aftermarket ones installed by a gunsmith. The Jewell's I had installed are set down pretty tight and I didn't want to be screwing around with them with no way to check them. With those you don't touch the trigger until your ready for the rifle to fire. They are a crisp 2#, but they feel WAY less when your laying a big ol tater on them.
If you DO work on your trigger it will quickly show in your groups. First they will open up, but once you get accustomed to the lighter pull they will shrink right back down.
Good Luck hope this helps.
