I third the suggestion to just start entirely from scratch and follow either generic (i.e. Park Tool) or Sram's own installation and adjustment instructions step by step.

For my own Sram Force FD used with a 50-34, I got it to shift very, very well doing the above. The critical parts that I think I improved the second time were the clearance above the large ring (I made it as close as I possibly could and still clear - a dime's worth at most), and the alignment.

For the alignment, after I thought I had it aligned parallel, it really didn't shift crisply up to the large ring. So, I turned the tail outward very slightly. It improved shifting greatly, and the chain rub and trim were still fine. My theory is that what I actually did was align it parallel when I thought I was turning the tail outward. Why? Because really it's kind of tough to actually figure out if a derailleur is parallel to the rings, especially with poor eyes and imperfect lighting. Looking at it now, it does look parallel, but it looked parallel before the tweeking too.

So, if after you really do a good job setting it up, it still doesn't shift well to the large ring, try turning the tail out a tiny, tiny bit and see if it helps. It could be that you're mis-estimating "parallel".
