The HN-2 is cool (if a little over-priced). It has metal threads and will actually accept filters, although Nikon warns against it for some reason.
I can recommend Nikon's polarizer; the rotating action is wonderfully damped like a manual focus lens, meaning it won't rotate on its own. It's a little expensive though. One word of warning, polarizers are really fun to play with and it's easy to get carried away making the sky too dark. It can make outdoor color photos look somehow "artificial", and too contrasty. One man's opinion.
Clear protective filters are a religious issue. I am a clear filter atheist (I don't use them). Nikkor coatings are very tough. But if using a clear filter will make you feel better by all means go for it. It's probably a good idea to get a multicoated one if you go that route. You don't need to sweat about keeping your lens elements completely spotless, some beginners actually mess up their glass from rubbing compulsively (trust me, I know this; the same goes for mirrors and focusing screens). I only clean my lens when there's something really nasty on the glass, like a big fat fingerprint. I use the highest-proof isopropyl alcohol I can get at the drug store, and a Q-tip. Finally, I use a microfiber cloth to get the last bits of cotton off. Make sure the cloth is perfectly clean (they are machine washable, but avoid drying with a lint sheet as this might leave residue).
One last thing, you can still buy brand new eyepieces, eyecups, and focusing screens for your camera. The focusing screens come with a nifty case and a special tool for changing the screen. You have to test your meter before and after installation, though. Oh, you can also get a back door with a film window. But I'm getting carried away. I just get excited talking about cameras.
