Good job Dave, should help make it shoot. On the ones I've had to add pressure points back into the forend, I've just cut small plastic squares(half of a finger from a shotgun wad come in handy) and add one or two till the groups come back. Then I'll add bedding compound over and under them to keep them in place and give a more uniform cradle to the barrel. As to the tang mortise fit, I've always been told not to let the back of the tang bear against the stock. Something about being a secondary recoil shoulder causing accuracy problems as well as splits. Don't know that it's true, but have seen it in a couple gunsmith books.
