Brian,
Now would probably be as good a time as any to paint, however a few things to consider...
1. Do you have a place to paint that you can control the temperature? Many guys have painted in all phases of weather, however, I can tell you from experience...painting in a space that will hold the temp fairly well is a good thing. It all boils down to the type of paint you use and your experience.
2. Remove the controlls? I wouldn't bother taking the controlls out...just cover and tape things off well.
3. If you were indicating the controll surfaces, yes...you will want to take the rudder, elevator, flaperons, and wings off the plane.
4. Make or acquire a pair of wing stands. You can find a couple versions here on the site. They are needed to paint the wings.
Hope these thoughts help.
