3) The "pre-allocate and Stuff" trick popular with mutable strings is not workable in T-SQL because the STUFF() function in T_SQL is NOT like the function of the same name in some general purpose languages: the T-SQL STUFF() is an RHS (right-hand side) function and NOT an LHS (left-hand side) function. AFAIK, there is no function in SQL that can (physically) write into a pre-existing string.
Oops, I just realized that I have a typo here. I reversed LHS and RHS in this statement. I will go back and fix it...
