Regarding setups...
I have a more holistic approach. I do it purely by feel. I just know how much a string will bounce for the right amount of relief for a low action setup, and likewise, for more of a Will Lee kinda' "I dig in like crazy" setup. Honestly, setup guides that give me specific measurements just get in my way. I also enjoy varying things with my mood. Like right now, I'm really into a fairly median setup. Gives me enough space to dig in and get that nice angry hard hitting tone when I need it, but then also does well with a lighter touch.
Bottom line is, this stuff is, and should be, SO totally subjective/personal, and it should change with our "musical mood swings" as it were.
Setup guides are GREAT for beginners looking for a baseline, but IMHO, that's all they should be. I've said it a thousand times, and I'll say it again... we should all be very well versed in doing our own setups, and not be afraid to tweak it one way or another over time. It's EASY, doesn't require any special tools, and IMHO, fun to mess with.
The key to the whole thing is starting with a bass that's made right... one that can easily take any type of setup without having to battle heel rise or fret level issues, etc... yeah, like a Sadowsky.
Peace.
