I set the screen to the largest size that will still let me select tools, shift cameras and access libraries. It's easy to crop in postwork and I need the large size because my eyes are getting old ;) First thing I do in a new project is reset the main, face and aux. camera's focal length to between 55 and 120, depending on how far away my character is going to be--the closer, the longer focal length used. And I switch off IK unless I can't get an extreme pose right without it...it annoys me. Textures I apply right away, unless it's Vicki3 in a complex scene. Lights I tend to leave for last and then tinker with them for-friggin-ever! ;)
