>I know there are beekeepers out there on this
list who have a lot of experience in this area and who do think they know
what they are doing.  What I would like to know from them is how much can
we really expect from any kind of bee breeding program?

I have lots of experience, but have no idea if I know what I am doing!  : )
My advice--you can realistically select for only one or two traits at a 
time, or you wind up sacrificing too much genetics.
I.e., years ago when I developed a line hygienic for frozen brood removal, I 
sacrificed some of my best producers, to my later regret.  I avoid 
sacrificing the best now, unless they have some really unfavorable trait.
