Thanks for the info and the encouragement. The DA line indicator is helping as I can now tell that my remaining gear shifting problems are more likely due to my bad habit of stopping my pedaling right before I shift. It's hard to develop a feel when my shifting gears doesn't give me immediate feedback from the derailers because I am not pedaling. Anyway, I've already started working on maintaining my cadence regarless of what I am doing (shifting, squirming in my seat, standing up to pull my shorts up, shaking out a leg, etc.). As for my speed, going downhill fast still scares me and I currently keep my speed from going over 22-23mph. On flats I usually go around 15mph, but I still die on hills. I plan on being 60 lbs lighter by this time next year which should help me with my climbing and my overall average speed.
