ok, in that case I would trade one of the griz pieces for a complete sigons set and start collecting p-gems to buy things like rockstopper, butchers pupil, dureals shell, a decent belt etc. trade other griz pieces for fairly costly things like draculs grasp and gore riders. although griz set is rare, the pieces arent really worth much, so I dont think that trades like this are all that unfair for you, especially when you think of it as trading stuff you dont need for stuff you do.
I would also try to concentrate on building a fanatic zealot as they are less dependent on +skills to be able to survive. mf shenk, eldrich and meph in NM for a while to accumulate better gear. the pits in hell are also extremely easy for a zealot as long as you get draculs grasp
anyhow. good luck
