John, it sounds like a good plan. The only thing I'd mention is that your pack seems quite too heavy.

You have to understand, though, that for this sort of trip, my pack would weigh about 11 lbs (including bear can).

That is a HUGE difference to lug up the hill.

When I've gone through hikers packs in an education program, I often find:

1. old stuff. Like antiquated stoves that are heavy.
2. Duplicates. You don't need changes of clothes. Be a little smelly, live life to the fullest.
You don't need camp shoes. You don't need wading shoes. You don't need shorts. You don't need complete cook kits. You don't need a cup and a glass.
3. inappropriate amounts of things. Ok, bring the hand lotion. Bring a 1/2 oz, not a quart.
4. people tend to bring WAY too much food.

the three worst words are "just in case"

All that said, I'm sure you'll do fine. Have a great trip.
