A circular polarizer (for glare and reflections) and a UV filter (mainly to protect your lens) and your set. For longer exposures there are a couple things you can do. Lowering the ISO will lower the light sensitivity (and decreasing noise). You'll need longer exposures to get the picture to have "normal" looking brightness. Decrease your aperture (the size of the hole in the lens letting light through). You do this by increasing your f-stop number. f-16 with ISO100 would mean you'd need quite a long exposure. I think I used f-16 and ISO400 with 20 second exposures for my astrophotography.
