Regarding alpha maps, you can do that with image maps as well as using
transmit and filter components in pigments, if I understand you correctly.
Otherwise, layering textures wouldn't make sense at all.  Maybe I
misunderstood.

Either mlpov or megapov has "finish maps", which I haven't tried yet, but
which sounds intriguing.  I think it's part of mlpov.

As for the texture includes, I generally start using them for test-renders,
and then end up creating my own textures, pigments, finishes, etc., as I
generally dislike the ones in the includes.  (Sorry)
