Congratulations, great deal and good choices!
I have the 16-35, but I don´t use it much. I don´t like the wide angel distortion you get beyond 24mm. Landscapes are OK, but people look terrible. I have also sold my 50L, because I am using the 35/1.4 (Sigma) and 85L instead. So from my perspective, you made good choices.
