DMT or EZE-Lap. I get better results from the interrupted plates over the continuous surface plates. Skip the 2X6 stones and get the 8X3 or larger bench stones. The DMT stand is a bit cheesy, so I'd get a better stand that is adjustable to fit a large variation of sizes.
The DMT duo sharp is what I would recommend. They are 2 sided stones with different grit on each side. Get the Extra coarse/coarse and fine/extra fine which should truly cover all of your needs. They say no lubricant is needed, but I use soapy water. Oil is not recommended. Dry the stones well after use or they will rust.
For ultra edge refinement, the diamond paste works well, but put it on a hard wood block. I use hard maple that is surfaced dead flat.
