The intro bit sounds great but isn't that difficult, it's probably the only slightly fiddly bit that you need to master for the song to sound right.
There's a lot of variation in the fills on the verses and choruses, if I had to learn it in a hurry I think those are the bits I'd simplify.
Once the song key changes for the main guitar solo and end bit it's really just root notes.
There are a lot of tutorials on Youtube, the frilly bits sound great but there's nothing that technically difficult in there, you may well find that you can actually master the whole song as played on the original recording in a couple of hours.
