No seriously. As far as that reel, you are kind of in a tough spot. First of all, I would rule out braids like Whiplash. I've heard bad things about Whiplash and Powerpro on any of the Penn spinners. Fireline is a great stuff. While the 30/12 might sound good, I heard it can be a little stiff. I'm using the 20/8 stuff and I'm very happy. The 6000 is about the size of my 6500SS so I'll give you a word of caution, pay attention to the line. Since you will be using line that is a tad bit thinner than what is recommended, you need to pay attention that it doesn't get screwed up.
As for a rod, I would say something in the 8-9.5 foot region would be good. You don't have to cast very far and a smaller rod will come in handy if there are other people near by.
For other things, a rainsuit and a pair of korkers. You need the Korkers DEFINITELY. The rainsuit is an option worth considering.
Oh yeah, don't wear your waders if you have them.
