Yep, sorry -- should've mentioned indexed shifters.

If you're turned your adjusters two turns, they're already a mile off and you pretty much need to start over. The park and sheldon guides are good for this. Once you've done this you can see if you're still having a problem. Rough shifting can be a bad index adjustment, or it can also be cause by a worn cassette and chain. You want to replace both at once, as they wear in together.
I'm not sure what you mean by "the RD needs to be pretty much aligned with the cog when it's supposed to be in the gear." -- the derailer should be lined up vertically beneath whatever sprocket the chain is currently on?
p.s. -- I was adjusting (loosening) the barrels based on the following from the sheldon site -- did I mis-interpret?:
"* Shifting to larger sprockets is accomplished by tightening the cable;
if such shifts are slow, the cable is not tight enough--
turn the barrel counterclockwise to tighten it.
* Shifting to smaller sprockets is accomplished by loosening the cable;
if such shifts are too slow, the cable is not loose enough--
turn the barrel clockwise to loosen it."
thanks for the response..
