I grabbed these a long time ago from:
http://forum.germanbrewing.net/viewtopic.php?p=2586. I think they are nice guidelines.

I would keep the water pretty bare bones...
Otherwise, use RO with enough calcium chloride to hit 30-50 ppm Ca, and let the sodium metabisulfite provide you with the sodium and sulfate.
I am only recommending noble-type hops for these recipes. It's fine to use just one, like Hallertau Mittelfruh, which works well by itself, or you could try blending two different varieties 50/50. Use what you like and experiment!
For hopping schedules, it is really up to you. A single 60 minute addition is fine if that's what you like. 70% at 60 min + 30% at 30 minutes is a really nice one for helles. 1/3 at 60, 1/3 at 40, and 1/3 at 15-20 is a great pilsner schedule.
As far as yeast goes, I've had the best results with WY2206, WLP835, and WY2124.
