to possibly help in the "vague understanding," the ()?: stuff is an inline if statement. (mynum > maxval) ? is like saying If mynum is greater than maxval. ":" is the else.
re your errors: from eyeballing everything, numberformatter.format returns a string (control click into ".format" in flexbuilder to see the framework code). I could be making this up, but NaN might be a class too, so it is probably the cause of your coercion error. I would break out everything into a function that returns a string (for the text property of your label), so the last part would be "return PrepForDisplay.format(mynum).toString()" (or "as String").
