Yes, no and maybe.
For some the specs on Jemsite don't even apply to their Jems (RG's, any similar guitar), let alone other types of guitars.
Myself, for example; I use about a .5 mm relief on my neck and 2.5 to 3.0 mm (high E to low E) string action. (Though lately I've had some pain in my bad arm so I may go back to 2.0 to 2.5 mm, but I digress . . .)
It's all a matter of taste, and the guitar.
Guitars with a shorter scale can usually have a higher action with the same string gage while maintaining the same feel, because there is less tension. These guitars can also get away with less relief; again since you can use higher action they will be less prone to buzzing.
Some people like their necks totally straight AND set their action ultra-low, buzzing or no buzzing, but these people usually never play through a clean amp and the buzzing is inconsequential to them, though it DOES hurt tone and sustain, no matter what they may have fooled themselves into believing.
As far as setting up a FR type bridge, there are only a few hard and fast rules . . .
DO make sure everything is tight
DO NOT over tighten anything
DO stretch your strings (BEFORE you clamp them)
DO NOT swing your guitar around by it (unless you can afford to fix it, or buy another guitar when you rip the anchors out of the thing
But the only rule that really matter is this . . .
DO set it up so that it feels right to YOU, no matter what anyone else says. It's your guitar, if I think it feels and sounds like crap, but you love it, it's perfect. :-)
