Sounds like you're off to a great start
. A couple of other little things that I forgot to mention which are quite important..............
RPM bumper
or
BRP bumper
I'm using the RPM one, but I'm sure the BRP one adds great protection as well.
Since you are going brushless you may also want to consider
BRP chassis brace
This will help strengthen your chassis and help in the case of any unfortunate crashes
