What is a maximum gap for tape spans? My wall span measures from ceiling joists to top of sole plate at 96.75 inches. I assume ceiling sheetrock first (1/2") which leaves my two horizontal wall sheets still 1/4" inch from sole plate. I want to catch this plate right? How much and then back to first question (a gap at top to tape and mud).

So you are saying that you will have 1 3/4" from the bottom of your rock to the floor? If that is true you can put a strip that wide at the bottom. Don't worry about taping it cause it will be covered by your base. Assuming you have base.
