Wilder fits the beginner role, in that it has the fewest choices available.
Divine can be had via Favor of the Martyr spell a.k.a. Favored of Ilmater, a 4th level "spell" converted, and with Sanctified Mind PrC.
Wilder 13 / Sanc Mind 6 and various exp burns along the way from making items (like any good 4e-er).
Check out the Mind's Eye at Wizards.com with the updates to Wilder.
Educated Wilder is mandatory.
Mantled Wilder can get any power via Substitute Powers from Ardent's update, and a liberal rules interpretation.
Lots of bonuses are available on the psi list.
Specializing in them alone is kinda weak, but still vaguely do-able.
Wilders need some of the fix-it feats that undo it's simple weakness, then it keeps up on the spells powercurve.
Int keeps up skills and social stuff.
Wis helps listen/spot and some feat qualifying.
