By default, it will assign equal costs.  Remember, though, that the 
OSPF specification doesn't define any meaning of cost. Much of the 
industry has chosen to use bandwidth-based cost, but you are 
describing exactly the sort of situation where manually assigned 
costs may be appropriate.

You don't.  Good encryption should remove all redundancy, so 
compression can't do anything with it.  You may, however, get benefit 
from compressing before encrypting, especially at an application 
level.
