Kim, which stone holder might depend on whether you want to sharpen over your kitchen sink or on the counter. You could use the universal holder over the sink as well, but you would need to build some kind of sink bridge to put in on.
I use the universal holder on my kitchen counter with some non porous grippy shelf liner underneath. I wet my stones as I go with a spray bottle. This works great with my Shapton GS stones, since they're truly splash n go.
Concerning the stones, the Shapton Glass stones are probably your best bet outside of something like Atoma diamond plates for these more wear resistant steels. If you're not taking off a lot of metal (changing bevel angles drastically, thinning behind the edge, fixing chips, etc.) the Shaptons might take a little longer, but they'll get the job done just fine - especially if you don't let the knives get too dull between sharpenings.
Other, more experienced sharpeners will certainly chime in here with their collective wisdom.
