One cautionary comment on Q2a, Q2b: As far as I know, you can't directly construct analogues of translation functors on parabolic sucategories, since the geometry of the full Weyl group plays such an important role. But Jantzen's translation functors do take modules in a parabolic subcategory to other modules in $\mathcal{O}$. By tracking what happens to simples and their projective covers belonging to a block of a parabolic subcategory you can deduce block equivalences indirectly.
