Highs hitting 50s and lows around freezing should consolidate the snow very nicely.
I wouldn't bother with snow shoes, just crampons.
I'll take some photos of course, but I wouldn't expect the switchbacks to be open. All of my discussions have been focused on the Chute. If you don't have boots/crampons, you might be able get away with spikes or walking crampons - especially if you're following tracks.
But whatever you do, bring an ice axe. I'd rather have trail runners with no traction but have an axe vs boots & crampons but no axe.
