@Rob: Thanks for the insight. How many nights did you stay out there? My plan is 6 nights at a nice, leisurely pace. PV, Woods Creek/JMT Jct, 2nights @ Rae lakes, Junction Meadow. I usually start early (on trail by 7AM) and get to destination around 2 or 3PM, the walk is half of the fun for me, I never tend to rush it. I tend to hike at a semi fast pace as it is but in the Sierras I stop and take pictures and just breathe in the surroundings. This keeps me from getting into a "slog". I have learned that my Boots are not optional to me from many long day hikes and backpacking trips. I have trail runners and don't use them at all for any hike with any weight (5# daypack or 30# backpack) due to very sore feet after using them. I've tried a few models and insoles. For me, boots=happy feet, non-boots=sad, hurting feet.
@Brian: Thanks for the ideas! I see some places that I can definitely shave weight. I am so used to "dry camping" that I almost automatically carry more water than I should in the Sierras. On the bandana/towel issue all I can say is that I am "A Hoopy, Frood who knows where his towel is." (For you "Hitchhiker" fans out there.) I have found so many uses for bandanas and towels that I tend to over pack them. I couldn't go with only one bandana/towel, but I can probably go with half the amount on the list. I see what you are saying with the First Aid kit, steaks, knife (I've been ton the fence about replacing it with a smaller pocket knife, you may have just pushed me), and extra batteries. The SPOT I use for my blog entries and personal fun, I love the track feature.
Thanks again for both your advice. I think I see potential for a few pounds of shaving. and if I can get the Helium Bag that will be a couple of more pounds.
