Also, from what I understand it scoops from the floats, but without enough airspeed it can't get out of the water..... and sinks.

That does not seem... like a desirable behavior. :p

What is the importance of the retardant being at its terminal velocity before reaching the ground?

And this is an awesome picture from that presentation (I diddled with the levels a little):

You ideally want the retardant to have no forward velocity. If it has forward velocity then it will cause shadowing in which it will hit one side of the tree and leave a big blank on the other side which the fire can break through.
