Brazing/welding mixed metals. Copper, Brass, Steel.

I saw Nelson's entry on Copper and Stainless cutting and welding, but I'm looking for different information. May I say that I've copied that entire thread and put it into a file for future reference. Fantastic information guys! =)
Okay, I'm getting into torch welding again after about 15 years and I've forgotten most of what I ever knew. The only torch welding I've ever done was strictly on mild steel and I'm wanting to work in mixed metals so I need some help. I picked up a small Oxy-Mapp rig with the intent of using Oxy-Propane once the first cylinder of Mapp runs out. I'm completely at sea on what kinds of rod to use for what material. I know that there will be a different material wanted if I'm joining steel to brass vs. just brazing or soldering copper but I have no idea what to use.
Can someone give me some guidelines on rod to material?
I am planning on doing just straight brass to brass, brass/copper to steel and brass to copper. Having not worked with some of these materials in combination with one another, I'm not sure how to proceed when it comes to welding vs. soldering them. Soldering for the most part is simple for me, but I really don't know at what point I need to change over to welding instead of soldering.
So, a couple of things defining my ignorance of the subject.
