What to put in the smoker this weekend?

Smoke 10 lbs of salmon in there to break it in!

That's just mean.

Nice try. I didn't say it was my first smoker.

We had that conversation on here before, where some people said they'd never smoke fish in their smoker, and there were the people who had actually smoked fish in their smoker before and said it doesn't leave any odors or taste behind so the first group is worrying for nothing.

So anyway, I think I'm going to try out my smoker for the first time this week and was talking to Jimmy James and asking for advice.
I found this video and this guy uses a tiny box for his wood chips. He talks about adding wood chips through out the smoke, but a 4 hour smoke seems much shorter than some of the stuff you guys post up. As this is an electric smoker with lava rocks over a heating element, is a smoke box like this guy uses the way to go? Should I be thinking about aluminum foil on top of the lava rocks to hold more wood? Please steer me in the correct direction. Also, where does the water pan go? Am I missing a rack?
