Vogelsang backpacking conditions

Heading out in a week for 3 nights, Rafferty Creek entry. Planning to exit Tenaya Lake or Cathedral Lakes trailhead. General route:

Rafferty Creek to Vogelsang toward Merced Lake to Sunrise Lakes or Cathedral Lakes to Tenaya exit.

1. Vogelsang Pass — worth attempting early June this year? Anyone done it recently or know current conditions?
2. Peaks — is Fletcher Peak or Vogelsang Peak accessible from Vogelsang HSC camp this time of year? Any other peaks in the region worth attempting solo Class 2-3?
3. Must not miss spots — Townsley Lake, Hanging Basket Lake, Bernice Lake all on my radar. Not sure if they will be accesible Anything else in the corridor I shouldn't miss? Any recommended epic camping spots? Something on a dome could be great,
