I have been on HRT since January. Hurting is good, because it means they are still growing. (Unless you bonked them, in which case if means be more careful!) A padded bra will make them less susceptible to bumping, as well as having other advantages.
Having widely-separated breasts is just a fact of life for trans women, due to the larger-than-cis rib cage. Just one more thing to make bra-fitting more diffficult; sigh. I don't know about them pointing outwards, but it is likely due to the shape of your rib cage.
