Here are answers to your questions:
1. Lets say you have attached part A to a solid. When you then attach
part B to the assembly of the solid and part A, part B will be attached
to the combination of those two. You have two options to attach part B:
you can attach to point or to face. When you attach to point you will
attach to a specific global coordinate which will not change when you
manipulate part A. When you attach to face, you can attach to a face of
part A, and when you then manipulate part A, part B will follow. So if
you want parts to follow other parts, you should use the to face option.
2. You should be able to manipulate any joints within a subassembly, so
you should be able to manipulate part X within part Y with the
manipulate joint command. Maybe you defined the joint of part X to be a
fixed joint? In that case you could clearly not manipulate it. If you
keep having problems, let me know.
