I use a Merkur Futur just like Gollnick's, and Derby blades. I bought some ridiculous amount of blades off eBay four or five years ago and have been slowly working my way through them. For the foam, I put a dime-sized dot on my palm, pick it up with the brush, and foam it on my face. The key is a nice hot shower immediately before to soften up my beard. You'll figure out your beard grain and how to cut it. It's just a time and attention thing. With the grain first pass, then I rake the razor across my grain at about 45* with an up-and-down motion. It's hard to describe. I got the idea from an old commercial that showed a guy sliding the razor across his grain from left to right so he slid the blade at an angle across his throat. I can't think of a way to write it down.
Picture this kind of motion: \/\/\/\/\ on a 45* angle with/across the grain.
Lots of ways to skin that cat. It's kind of like making a French trifold omelet. The technique is much more important than the eggs, butter, and salt. Take your time to learn what you like. Wet shaving is cheap and your gear will last you a lifetime.
