Well, the former is fairly straightforward, you can just start unrolling things in the direction from which they came. Step 1 is probably a balanced budget. Taper off federal government funds to the states over a period of 5-10 years (this should not be happening in the first place). Axe the dept of education, eliminate loopholes from the tax code. All this stuff has been done to death before. I'm not sure what you're looking for.

Oh, and let's not forget... Nuke the federal reserve from orbit.
