The black deluxe set comes with (almost) everything that you need to get started. It comes with the black console, power brick, sensor bar, HDMI cable (if you need component you'll have to pick it up separately), stand, tablet, tablet charger and dock, a plastic stand for the tablet, and the packaged-in game NintendoLand. What the game does not come with is one or more wii remotes. If you already have a Wii, you'll be able to use your current remotes.
I would recommend the Deluxe model hands-down, there are too many extras that will save you money.
+++++ Nintendo Deluxe Points Rewards means you'll be saving about 10% on ALL purchases from the digital store.
+++ Cradle makes charging the tablet simple and protects it
++ Nintendo Land is really fun and shows off a lot of what the system can do
++ 32GB makes downloading multiple games possible even without a USB hard drive
+ Wii U stand is simple and fits snugly, making the system look great.
