I just had both replaced 14,000 miles ago, now the water pump is leaking. Also leaking out of 1 head. Never overheated. Should I use all Subaru parts to replace water pump and head gaskets, etc.?What about new head bolts?

Question: Do I need to repace the timming belt if replacing the water pump?

That year range for the 2.5L engine did have head gasket problems. The engine has to be removed to replace the head gaskets. I have not had to replace the head studs, a good quality head gasket timing belt and water pump are as good as Subaru. If the belt is contaminated with coolant replace it, check/replace all front oil seals and tensioners. Unfortunately a big/expensive job.
