I'm refinishing all of my exterior doors in my home and would like to re-do the surface with a gel stain. Do I need to do any additional sanding to the stain that I just applied before applying the gel stain, or can I just apply the gel on top of the new stain?

I would check to see what the manufacturer recommends for their stain application first. Staining over a stain can create some problems, i.e. poor color penetration, poor adhesion, poor color consistency. However staining over a stain may be necessary to achieve the look you are going for. I would try to simulate what you are going to do on your doors on a separate piece of wood of the same specie and see what happens. I always try to simulate exactly what stain effect I plan to do on a separate piece of wood first, let it fully dry, and then finish it with whatever finish coat it is going to get. It is way easier and cheaper to experiment on some wood scraps than your newly sanded and stained exterior doors.
