Bathroom wall and floor convergence?

What's the best way to handle where the bathroom wall and floor meet? I know you can do tile to tile, but how about where a stone tile floor and drywall or backerboard for the wall meet? Of course I'll grout, then seal the grout and then run clear silicone along the grout line to prevent leakage, correct? Can I put wainscotting and trim on a stone tile floor? I totally forgot about this aspect of doing tiling myself. And should the tile go under the backerboard or up against it. I'm thinking against. Any help you all can provide will be appreciated. Thanks.
