I have to admit that I really don't have any good tips but here is what I do:

1. Clean up the receiver threads with a steel brush and wipe out all the factory lube. Lightly lube with tetra grease.
2. Check the firing pin protrusion and set to .035"...it's usually a bit longer from the factory.
3. Set trigger spring tension to minimum. Cut down the safety blade spring to just where it's holding the blade out.
4. Chase scope mounting holes with tap.
5. Change action screws to grade 8 cap bolts.

Your steps have me thinking about what a basic DIYer could do. It might be cool to write up all the steps and take pics of things that someone with simple hand tools, a dremel, and some sandpaper could pull off to help accurize.
