A penetrating sealer is what you want to use on grout but it's not like painting a protective coat on a piece of wood. The sealer soaks into the grout but allows it to breathe. I've sealed probably a few hundred showers, mainly from builders and designers saying it really needs it. I didn't seal my own shower.

Mold feeds on the soap film, keeping it cleaned off goes a long way. Even though I don't do it, a lot of folks recommend wiping the shower down after each use and I can see that helping as well.

I wouldn't silicone over the grout. If I plan to silicone the corners, I avoid getting grout in that joint. Any grout that I get in it can be raked out while washing. Then add the silicone after the grout sets.
