Toward a press handstand

I split a semiprivate handstand lesson yesterday, and it was AWESOME. This kind of thing is exactly what I need. And by "need", I mean it will definitely help my handstand over time, not that it will do me the slightest bit of good in yoga class two hours later when my shoulders are considering mutiny. But anyway, it was intensely valuable to get a real evaluation of where I am with respect to press handstands and various press handstand drills, and come away with a list of relevant exercises that I can actually do. It's so incredibly great to have an acrobat teacher in town!

I haven't put these together into an actual exercise routine with reps, timing or sets yet, but here's my basic homework that I can do in addition to just practicing balancing my handstand, and my usual shoulder stretches.

What	Why
Roll through my middle splits repeatedly, as well as I'm able (this means lifting up and over them), with hands outstretched. When lying down forward of feet, try to tuck the pelvis.	For a wider straddle. This is exciting because I want that anyway, and often have responded well to repeating brief stretches 10 or 20 times. Why've I never tried this?
Headstand curl-ups and curl-downs, pressing, all the way to/from knees if possible.	Train myself how to roll up and roll down. My regular headstand presses are great, but I'm used to doing them with a straight back, even when piking, and curling feels very different.
Press handstand against the wall (negatives; later, with jumping up?)	Train myself how to roll up and roll down. Probably I'll be starting with just partial negatives, just to the point where I start to lose it (which happens fast).
Banana handstands with really open shoulders, everything arched back	Get my shoulders used to being really open but with weight on them.

Anyone who might have suggestions on how many times or how often I should work this stuff (ahem, nevers), feel free to give advice. :) I'll be experimenting today soon to see what feels right.
