Dr.Dish:
You could use a h2h-actuator made for a larger dish as you use. He will need
less force to move your dish and as a result will make less noise. But also
a normal actuator will do it.To tight the actuator on his middle part will
prevent him to bent over a little after some month  and making terrible
noises. Many people mounting the actuator on one ende (near the dish) in
order to get more satellites to the east or west.
Between the dish and mount (usually 4 bolts) you could place some plastic
rings. Noises coming from the motor and polarmount will be less reflected by
the dish.
The mounting pole could be filled with very fine sand or some foam-spray. A
last way is to slow down the motor by connecting a power resistor to the 36
volt supply
