"Idiots Guide" to basic IRS related info?

I find myself needing very basic reference information I was SURE would be handy to find here.

Things like:
How to properly measure a CV (and other) axle for length?
How to include the CV joint in measuring axle length?
Desired minimum and maximum CV angles?
Are CV joints as finicky as U-Joints for the angles at each end not matching?
Light hollow CV driveshsfts? (trans to diff).

Basic ralationship of roll center, instand center, camber caster, etc. to handling?
Basic starting points and the direction you want them to go?

Seems most discussion here assumes the reader is already fairly expert, not all of us are.

Most of this CAN be found via searching the web but it seems to me that this site could be a little more "One stop shopping" friendly if these and other basic topics were added.

Not criticising, just a suggestion.

Poking around the web is seems ideal CV joint angles are between 3 and 15 degrees with a momentary maximum of 35.
Some angularity is necessary to circulate the grease and minimize heat.
So having the arms canted back or forward a little while also "Level" at resting height is a good thing.

Thompson Constant Velocity Joint
Ralphy posted a video file showing a 3D rendering of this device a while back.  Looks expensive to produce, but quite ingenious.
