AC Delco sells aluminum coolant elbows. They are probably just repackaged Gates elbows, but don't buy the Dorman ones from the parts store thinking they are the same - unless Dorman fixed their issue, their o-rings tend to leak.
Other than that, you have to turn the power steering pulley in order to access the bolts mounting bolts for the power steering pump through the pulley. The PS pump has to come off the engine to be able to access all the bolts for the water pump, but you don't have to disconnect the PS hoses at all. Make sure you get the mounting surface on the engine block completely clean without gouging the mating surface.
It's a good time to do a coolant flush as well, and you can pull the forward knock sensor (just forward of the oil pan) with a 22mm socket to drain most of the coolant out of the water jacket in the engine.
