Sarah, I think it would be easier just to learn the fingerings for the chords in the key of E than to fool with all that retuning stuff--Seriously, unless you have a really good capo, and a pretty good guitar, you will have some intonation problems playing with that capo on the 9th fret--If you don't know how to play in E, maybe you could play it in D, and put the capo on the second fret--
