For float fishing, personally I think the rod is more important. Actually in general, the rod makes a bigger difference I think. And get good hooks, I like Owner cutting point #2 and 1 and Seaguar flurocarbon.
Sea Run is an awesome shop with great staff, Andrew and Cody will set you up right.
I ordered all my wading gear from LL Bean.. $79 for waders and going on my third season (breathable stocking feet) and just got my Goretex Paclite wading jacket from them ($149 on sale). The jacket is awesome, all the features I want and it looks good enough to wear around town. I am very happy with their stuff. Whatever you get, go breathable and think modular, as in layering system.
Buy good boots.
I'd get a low profile baitcaster, but nothing wrong with getting a centerpin. May take you a while to bomb casts so you can fish more spots, especially when you may not have too much choice with where you can drift because the river is busy during salmon season.
I'm still at the stage where, by any means necessary to get into fish... then good line and hooks so I don't lose them.
Good luck. And if you have the cash, buy whatever you like. Nothing wrong with being a gear who*e.
