need help finding a new Piano Keyboard

allright, i'm deciding to purchase a new keyboard, but i'm sort of picky on the type i want.

see i'm getting it in order to bypass having to take up music lessions to learn around 4 songs.  i have no idea how to read piano sheet music btw so this is what i'm looking for in my new keyboard.

-teaches right hand AND left hand parts of the song, with the ability to switch between one, or the other, or both

-keys that light up in addition to the LCD screen which shows you where to place your fingers

-teaches you the FULL song, not just 1/2 or 1/4 of it.

-must have songs are

                                  Fur Elise

                                  Pachelbel Cannon (D Minor)

                                  Moonlight Sanata

                                  Claire de Lune

the first 3 songs are musts, and the 4th is one i'd like to have in the song bank.  again, i want the full song, not just part. 

any suggestions??
