You mean stuff like clearing Coil in order to progress into HW or the Alexander raid?
The answer is, no, you do not need to do those things. Yoshida mentioned it in one of his interviews.

As far as I know so as long as you are caught up with the main storyline, you should have no problems in enjoying HW in all of its entirety.
