Wii accessories advice needed. Will you help?

We helped the economy over the weekend and bought a Wii and Wii FIT. Yes Thank You for all your applause!

We know we need another remote controller and nunchuck. I suspect we also need a charger for the remotes. Do they now make non-Nintendo remotes, nunchucks, and chargers? If yes what are the good ones and where do you buy them? Or should I just bite the bullet and buy all the stuff at Hollywood Video/Game Crazy? (They seem to sell everything at the Wii allowed lowest price.)

I saw non Wii brand wheels for Mario Cart at HV/GC for about $8. Are these just as good?
