I'm a little puzzled at why you are tinkering with the limit screws.
The last bike I was messing with, I replaced the chain and cassette. Then set the limit screws by pushing the derailleur by hand without a chain. It worked pretty sweet. Then no more (significant) adjustment of the limit screws once the chain was in place.
Use an inline barrel adjuster (or at the derailleur or cable stops) for fine tuning the shifting.
If you're got 9 shifts, then not hitting the 10th shift, then back off on the barrel adjuster slightly.
Is the cassette tight on your hub? None of the sprockets move, right?
Bad shifting is sometimes caused by bad derailleur cables and housing (non compressible, lined?)
