1) I do think you got a fair deal. I HATE bundles where you can't choose what you get, but if that's all that is available, and you want one, then you don't have many options. Like you said, better than $350+ for console only on Ebay. It's certainly cheaper than a lot of other bundles, also. You can always sell the unwanted extras on Ebay or Craigslist, and get what you want.
2) Some fun two player games.... Wario Smooth Moves (have to get through it once to have multiplayer mode, but it's worth it and you can take turns until then), Wii Play, Carnival, Rayman Raving Rabbids 2, and I've heard Mario and Sonic Olympics is great.
3) Only you can decide if you made the right choice. Not your friends. It depends on what YOU like, and prefer. Sounds like you may have a bit of buyers remorse, because that IS a lot of money. But based on what you are saying, it's what you are looking for! The Wii is TONS of fun. Enjoy your purchase!!
