All of Blackdog's answers are pretty much right on the money. For #2 though, the "line" between low and average is 6/7. Low he can have 0-6 points remaining, average 7-20. Low/high is 21-27. High/high is 28-?. In other words, there is no "set" cap to what high/high can reach (besides 100 of course).
He is correct about LP and Per showing the crazy amounts of growth, guys have gone from the teens up to 100 in those two categories. The other categories, for high/high, can reach high 30's to low 40's worth of growth, but that would be close to the very limit.
For #1, you can also go to a player's ratings history tab, pretty much figure out where the change from average to low happened, then add 6 more points to that and that will allow you to find his max in that category. In fact, you can use that same concept to get a rough estimate of where ALL of your player's ratings are going. I've not heard anyone mention that yet, don't know if everyone was holding that close to the vest or what. Surely other coaches must have realized that by now.
As far as documents, formulas, etc., all of the questions you've asked have been answered numerous times. You simply need to use the search function for the HD forums and you'll find everything you need plus some.
