The main things you need to do are in other areas:
- Make sure that the shower area is properly ventilated. Install a fan if necessary.
- Make sure that as much of the water can drain away as possible.
You can seal the tiles after installation which will inhibit the growth of mold, but make sure that the grout is completely dry before application.
You can also use anti fungal cement and grout to inhibit the growth, but this would only have a minor effect.
Joe, sorry to use the "answer" function again instead of adding another comment, I wanted to attach more pictures.
The tile I used was not available with a bullnose so I finished it flat on the sidewall. The edge cant be seen normally so I did not spend time making it perfect, but for your situation I retract my note about never finishing an edge with caulking. If you end flat to the wall around that corner it would be perfectly fine to use caulking for aesthetic purposes, use paintable caulk so you can paint a straight line down the whole side when you paint the wall.
Sorry I misunderstood your question, my situation was similar to yours and wrapping the tile around to the outside seemed like the best solution for me, and it looks pretty good that way (at least my wife did not complain, that's all that really matters).

This is not prepared for use in a shower. The seams of cement backer-board should be filled with mortar prior to application of the mesh tape. Also, it is not waterproof yet because it needs at least one more coat of waterproofing.
You had better take a good look at the pan; how it was constructed and prepared. A bad pan will make for a really bad day for you sometime in the (perhaps near) future...
