I always use my bow square to measure brace height. I'm not really worried about what it is. Just use the same tool from the deepest part of the grip to the string every time.
Measuring A2A? Whether you measure from outside to inside, center to center, or inside to outside doesn't matter. The measurement will be the same. The only thing that might make it vary is whether there is any cam lean (limb twist) so you have to careful to measure it on the same side of the bow all the time.
But if you shoot the X Cams this shouldn't be an issue either.
Tecnically true BH is measured from the deepest part of the grip to the inside of the string at rest.

But like Bfisher said as long as it is in the ball park don't worry about it...as long as the arrow lands weare you look that is what is most important.
BTW I have actually, purposley made my AtoA longer to take advantage of limbs that were to heavy and to shorten a given draw just a tad.......the draw part doesn't nessicarily work on parrallel limbed bows...think about it for a moment and you will understand why.
As far as measuring BH measure it with whatever you have that is accurate a ruler should be fine.
What I done to my bow square was to use some of that yellow ruler tape (only thing I know to call it) it imeasures a foot and then starts over again....anyway I put this along both sides of my square Its easier to read and accurate.
