DUG, I owe you one from our discussions a couple of years back. I'd love to share some trail time with you. I know this peak well. I haven't decided what to do around next weekend, but it could easily include Mt. Muir, which would be my 37th ascent of it. I climb it class 3, but I have seen and removed many rappel slings from the route, so some treat it class 4. I wouldn't argue with them; climbing difficulty is subjective.
Based on what you've written, I think you would do fine on Mt. Muir if you went with someone who's climbed it before. Also Split, Williamson, and Tyndall if by the easiest routes.
The others? I'll defer my recommendations until we've shared Mt. Muir. As Bob West suggested, too many people offer climbing advice to those whom they've never met.
