I'm doing the same, and I'm in progress of working on the cosplay.

Wig is the only real option, and while it's not ideal, you can always ask cosplayer and wig-makers for advice on styling, so look around on Deviantart and Facebook groups. I'm lucky, being a member of one (and I'm known both as one of a group of Deadpool, and a frequent One Piece cosplayer, Sun will be the first not connected to either), so you should be fine there.

As for the staff, it's really about how well you can make it, and how good you are with the nunchucks. I was going to be working with wooden dowel and just make the staff, not the two gunchucks. If you do decide to go for combining both, it'll require a lot of engineering, and as a relative novice cosplayer, I couldn't help you design such a thing.

Good luck, you should do fine.
