goo to see youre now out there having a crack..
there are a cpl of schools of thought on slowing, but i'd guess that most here would subscribe to the one that says somehting about being in a gear that will "drive" the truck out of trouble, right up to the point where youre might be rolling along >5km.h.. all depends on weights (you can get away with a bit more brake usage, empty) really and traffic..
I personally prefer to always have a gear handy.
the best way to get familiar with changing down the box is really to take note of what rpm = gear = roadspeed. i think it was explained earlier, takes alot of practise
