This is in the original key - being G#/Ab major (same thing). 
If you want it easier transpose it down one step and put it a capo on first fret. 
Being a piano player I tend to put add9s and maj7 everywhere. 
But if you wanted to add them I'd suggest a maj7 on the Fm chords and add9s on the C# and D#.

Hope it's all right! First tab so, here goes.

Nita.
