My questions are: Do you need to buy the points card to get the games from virtual console or can you use a regular credit card and buy them directly? Can you use a GameCube controller on all classic games or do you have to have the classic controller? Is there any word on whether super Mario brothers 1, 2, & 3 will be available? What about a link to the past? Are they releasing any GB or GBC games for the virtual console? I do not want to invest in a points card and classic controller if I don't have to.
You can buy points with a Visa or Mastercard in the Shop Channel, where there is a button that says something about buying Wii points. After you click on it, you can choose between paying with a credit/debit card or a Wii Points Card. The Controllers you use with games vary from game to game but if you select a game, in the details it shows icons of the controllers you can play the game with. To the best of my knowledge, the Super Mario Bros. games you mentioned are already avaliable. I do KNOW that the have the first one, though. The last of your questions, unfortunately I can't help you with.
