If an indirect method claim 1 has 6 steps, to infringe that claim one entity must perform all 6 steps. A different claim 2 depending from 1 essentially says "do all those 6 steps **plus** these two more steps. To infringe 1 you must do the 6 steps. To infringe 2 you must do the eight steps. In both cases it is **all steps** of a particular claim. Anyone who infringes 2, is by definition also infringing 1. If you are doing all 8 steps you are obviously doing the 6 steps.

"Means", used in a U.S. claim, has a very specific, and somewhat counter-intuitive meaning. There is a claim form that intentionally uses the word means. It is not used very often. Throwing around the word "means" in claim that was not specifically intended to invoke a particular paragraph in the patent law is to be avoided.

As a goal you want a range of claim types and scope and you especially want claims that are actually directly infringed by the hypothetical "bad guy" with the deep pockets who is profiting from your work.
