Ego Whip is 2nd level, actually. But I can see why you'd pick it instead of a 3rd level power.
I don't think Psionic Meditation is going to be as good for you as you think, unless you also take Expanded Knowledge: Hustle. Manifesting an Astral Construct is a full round action, and so you won't have a Move to refocus while doing that. I guess you could toss out a construct, then manifest something else next round and refocus. I usually found that just having Psicrystal Containment was plenty good on my Shaper, though. I rarely needed more than two focuses per encounter.
And what makes the Vigor/Psicrystal/Share Pain combo so delicious is that the Psicrystal gets the same temporary hit points that you do from Vigor
for free via Share Powers. So once you have Share Pain going, you basically get 10 temporary hit points for every power point you pump into Vigor. And if you don't get Vigor up in time, you basically get double healing via Share Powers + Psionic Repair Damage. Warforged shapers are awesome...
I'd probably skip Greater Concealing Amorpha, if you go with the Vigor/Share Pain combo. I dislike the short duration, and you're not going to want to waste many actions buffing in combat. Linked Power can help out greatly with that, but I'm not sure what you'd replace with it, and you'd wind up burning through your focus a lot more with that (and need Hustle + Psionic Meditation even more).
