Timothy Ferriss has a lot of fitness and nutrition advice in the bestseller 4-hour body. He advocates one-set-only (per muscle group) workouts. Is that good advice?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
Thanks for posting this. I've read/reviewed the one set approach and I think it's worth trying. Like any other approach (steps/pyramid, waves, etc.) - they probably all work, but not forever. I think there's a 2-3 month period where you will see gains and then the body adopts/adjusts to the routine, at which point you need to change.
It depends on what activity level you are at and what your goals are. Like a lot of programs you will see progress but eventually your body gets efficient at it so it's best to change up exercises every few months.
If your goal is...
Fat loss - you can't target fat loss. You can do a thousand crunches a day and still have flab on top of your incredible six-pack.
Sculpting/Toning muscle - you need to have muscle first in order to tone it. Any weight lifting regimen will build muscles for you. For target-specific exercises - I'd just caution against getting a muscle imbalance (i.e. making sure if you work biceps, you work triceps too, etc...). Having one muscle stronger than its opposing muscle will make you susceptible to injury.
Any exercise is better than none.
