I'm glad this thread got resurrected... I can't believe I missed out on all this fun last month!!!
As for intonation, I've never heard of saddles being arranged by look, rather by lengthening or shortening the string as needed.
And which way the adjustment screws face... I've never really given it any thought, just assumed they would always face the stop bar (both of my LP's have Nashville bridges).
At the end of the day, it doesn't matter how you arrive at perfect intonation, as long as it sounds good (and is in key). What works for one person may not work for another, and I'm certainly not going to tell someone their method is wrong because I disagree with it.
