New gaskets should have lasted longer than that. Sounds like the head may not have been torqued down correctly or one of the heads was warped, or the surface of the block had already been damaged (ie. pitted) or not cleaned properly. Ya, $1800+ is the typical charge for V6 HG job. If you don't do it yourself, your almost better off putting in a used eng. from japan. To re-torque the heads, you pretty well have to do 75% of the labor anyways, so it's never worth doing just that on this engine in my opinion.
You can likely get by spending about $400-500 on new head bolts and a gasket set, and the rest your labor. This is assuming of course that the heads don't need any resurfacing and no valve job. It's better to buy indivdual gaskets and then the MLS rubberized HG's for this engine from Napa (Victor Reinz) if you want to do it right and have it last.
Book rate labor is probably about 10-12hrs at a dealer.
As to which came first, hard to say. It may have been the HG leaking and causing the cooling system to overpressurize and stress an already brittle plastic rad, or it could have been the weak rad that was never replaced from the first HG job and an unchecked low coolant level from a slow leak in the rad. Who knows really?
