ZDDP for short is Zinc. zinc adds a protection barrier between the camshaft and lifter without it it will aid in wiping out the camshaft lobes. Roller cam do not have this problem but flat tappets do. I second on the VR1 oil because it contains ZDDP. I would run DEX III in the transmission. You may only find it as Dex/Merc though and is the same thing.
