Bullnose tile, start and stop tiling job

Getting ready to tile my first shower. Planning to start at the bottom and work up. Do I place the bullnose trim alongside the courses of tile as I go up? Or finish the big pieces then place all the bullnose pieces around the edge last?

While on the subject, is it ok to finish a few courses then come back the next day to finish, or should it all be done at once to avoid the thinset from drying out between courses? Is there anything I should do to clean the edge where stopped tiling for the day to ensure a good continuity when I restart? Thanks for the input
