I've just finished going through all the books I thought of to find psionic powers, and made a complete list of them. Key to this is that I made the list by discipline, because when I was considering what Favored Discipline(s) to pick for my Erudite, I couldn't find any power list that made it easy to determine exactly what I would get by choosing that as a favored discipline. The powers restricted to psions of a particular discipline were easy, but favored discipline makes ALL powers of that discipline into standard psion/wilder powers, so it was much more difficult to determine what I would get from other lists, like powers that are only on the mantles, and powers from the Psychic Warrior and Lurk lists.
Therefore, here is a full list of all psionic powers from the Expanded Psionics Handbook, Complete Psionic, Secrets of Sarlona, Stormwrack, Races of Destiny, Races of Stone, Sandstorm, Weapons of Legacy, Races of the Wild, Dragon Magic, Races of the Dragon, Frostburn, Magic of Incarnum, Faiths of Eberron, Magic of Eberron, Player's Guide to Eberron, Races of Eberron, Dragon #317, and the
Mind's Eye 3.5 Compilation PDF. (Some are double-entries because I included the same power from every book it appeared in, rather than just one instance of it).
Psionic Powers by DisciplineThe second unlabeled column is the level at which an erudite without Favored Discipline would normally gain access to that power. Any powers they can't normally learn are marked as - and powers marked 10 aren't available before epic.
I may work some more on this, adding some basic descriptions and such. If anyone has any additional sources I didn't think of to check, I'd love to hear about them so I can add those too. I might turn this into a proper handbook at some point, but for the moment figured it's just a useful list.
Observations and comments: Metacreativity, which was originally one of my top choices, has very few powers that are otherwise entirely unavailable to the Erudite. While some of its powers are exceedingly nice, the Erudite eventually gets all the best ones anyway if the game goes epic. Genesis is the only one from there I would really, really want that I can't get pre-epic, and even that one could, potentially, be obtained with psychic chirurgery. Psychometabolism, however, remains top of the pile - and perhaps secures its position as #1 pick, as it has the largest number of otherwise unavailable powers, several of which are very nice. It also of course contains Metamorphosis and its greater version, meaning earlier access to those.
