The word "helm" can be used, but it generally refers to the entire steering mechanism, whether it's a sumple rudder and tiller, or a pneumatic wheel. I'd normally say "wheel" to differentiate it from a tiller, and to single that particular piece out from the entire mechanism, but "helm" is also fine.
Usually they call them kick panels or lower kick panel.
Austin's last name is Moon.
Austin Phelan's birth name is Austin Phelan.
Teri Austin's birth name is Teresa Austin.
The proper term is helm. Hence the person doing the steering is called the helmsman.
