Success!  The halibut came out GREAT.  I watched it carefully like you suggested, HJP -- moist, flavorful, just awesome.  I got some wood chips awhile back at a local gourmet shop -- a combination of alder, chardonnay, and mesquite.  Very tasty.  
My salmon turned out a little too salty... I did the brown sugar rub overnight (my first mistake) and didn't rinse it thoroughly enough (my second mistake).  It's still good though -- the thicker pieces aren't quite so salty.  I'll vacuum seal and freeze it and use it for stuff like cream cheese.  I like whipped cream cheese with salmon and fresh herbs.  Sure makes a mighty tasty omelette!
Hey HJP, if you're coming up for dinner tonight, can ya bring me a couple of briskets?  Can't find one anywhere in this town!!!  /infopop/emoticons/icon_razz.gif   Oh, and I'll take a couple of those halibut steaks, too.   /infopop/emoticons/icon_wink.gif
