I would look at them in reverse order (Bottom-Up).
The Smellenbergh Isosurface Manual is great, and it describes many
possibilities, but it's not a tutorial in the first place.
The second one is a good reference for the build in functions (so is the
manual, though).
Samuel Benge describes the basics (I didn't work to much with it, but it
seems to be a good place to start)
All this is just my humble opinion of course.

Isosurfaces are great. A bit slow perhaps (no not really if one looks at
what they are doing - but you get some long renders if you are not careful)
but really great if comes to small structures and you don't want to use just
normals.
