Replaced "affine" with "dotted" as per Jim Humphreys' suggestion.

You should look at two papers: Garland-Lepowsky, Invent. Math. 34 (1976) (online at gdz.sub.uni-goettingen.de), and Lepowsky, J. Algebra 49 (1977). The classical BGG resolution and resulting Bott theorem on cohomology of the nilradical are treated in my 2008 AMS graduate text. By the way, your "affine action" must refer to what is usually called the "dot action" of the Weyl group, with the origin shifted by $-\rho$.
