Personally, These are the changes I'd make to your list:
Nintendo Wii (With WiiSports, Wiimote and Nunchuk
Guitar Hero 3: Legends of Rock
2nd Set of Wiimote WiiPlay + Nunchuk
Need for Speed: Pro Speed
Prince of Persia: Rival Swords
Metroid Prime 3: Corruption
Legend of Zelda: Twilight Princess
Super Mario Galaxy
Resident Evil 4
And I would reserve Super Smash Brothers Brawl and Mario Kart Wii. I personally wouldn't get Guitar Hero, but thats purely because it isn't a game I like, its a great game, so I left it on your list.
Good luck and feel free to ask if you have any more questions.
