For the first two points, a partial implementation is already done here: https://github.com/fabe3k/mesa/commits/tessellation
This predates the addition of ARB_separate_shader_objects, which has some interactions. There are probably also plenty of rough edges, but it should give you enough to get started with the gallium/tgsi parts.
