Chunks, no. Chips, some guys do and some don't. I don't use chips anymore, but did soak them just so they didn't ignite and burn up too quickly. It made them smolder longer. I only use chunks now. No soaking required and smolderes longer.
Edit - I don't season fruit wood, but do with but wood. Personal preference. I would just play around with it all while your cooking and see what works best for you.
