Optional depending on what you want. Are you expecting an 'estery' finish with the yeast?
complimentary hops wouldn't hurt but depending on the strain it may not be needed.
I did a couple last year, Belgian yeast fermented IPA and one done with French Saison yeast. I got a very nice mandarin orange from the French Saison, and a bit of citrus forward hops helped get a nice aroma but not overpowering.
