That will work.

Jesse Sheidlower saw about an order of magnitude performance difference
with Maypole when using caching, but it depends a lot on the complexity
of your templates.

That will work fine as well.

It might not catch deletes.  It does catch modifications.  If deletes
happen often and you need them to be reflected immediately, you could
subclass the Template::Provider to check for that.  (I think that's the
right class.  Might be worth asking on the TT list to see if anyone did
this already.)
