I think you have a great list going here Carl -- everyone is spot on.
I was just going to add that if you find yourself facing a long glide with visible fish dimpling the surface and eating what you suspect are midges, you should consider bringing a midge pupa to hang in the surface film. There is nothing easier than an Al's rat for this purpose. A size #20-22 in black or olive works. The few times Beth and I have needed to "midge", we've basically had luck only on this pattern fished in the film -- and we've take a couple of nice browns with it. I think the pupa is really the important life stage when you *see feeding. I don't even carry adults.
A tiny (#18-20) bead PT nymph (or wd-40, or zebra midge) works great. I'm not sure one is better than another. We basically don't even use dropper nymphs larger than a #18 anymore. Well, technically I use a #16 wet hook, which is like a 18-20 in profile but with a bigger hook gap.
For dries, you only need 2. I'd carry a #14 CDC and Elk (heavy on the hair if you are fishing rough water -- light and sparse as possible for flat water....in other words, have both), and a #14 CDC "Puff". This began as a CDC comparadun, but with PT fibers instead of microfibbets. Then, I started using more CDC for better floatation. Frog's fanny with the brush really helps. Now, it's just a wad of CDC wing on a light 103bl hook. Anyway, it's the best selective fish dry fly I've ever used and we've taken a lot of fish with it. Beth took a nice cutthroat with it in CO, and if you're working a fish that keeps exploding on a piece of water but won't take, you can usually get 'em if you clip off that crappy #16 parachute adams and come back with the more lifelike CDC dry ;).
We don't fish parachutes, but I did pull another one out of a tree 2 weeks ago that someone else was clearly banking-on.
I don't know anything about a rubber legs and rarely fish streamers for trout, unless it's for stockers. Then I just use a bead woolly bugger of some kind. Any kind.
Have fun! Been in CA (Los Angeles), and onto MO soon.
