Sengmeng, I really like the ideas thrown here, but I have a few concerns.

Psionics
This feature is pretty good, and while I won't really comment on how balanced it may or may not be to remove components in most cases (I personally don't think it's a super huge deal, but a lot of people disagree with me and say it's huge), the biggest concern I have is that it also removes costly components; any spells that normally have a cost can now be cast for no cost (aside from a spell slot, of course).

Body Sculptor
What exactly does it mean by "Alternatively, he may choose one of these changes to have for the entire day."? Does this mean you can choose one effect when you cast a spell, but cannot get the rest? Or can you just have them for the whole day instead of a few rounds? I would assume the former, but you should probably clarify.

Psion
Some clarification is needed, here; can multiple points be spent on one cast, or only one?
