Sound like you're on the right track. I do a Kauaii trip each year and according to the local net fishermen there are bonefish around. Expect all sorts of stuff inshore around the reef edges. I would pack a few deceiver/general baitfish patterns as well as the usual bonefish stuff.
Have fun & let us know how you get on. This is a relatively uncharted area for the long rod.
When sight fishing, look over your shoulder from time to time, you never know who's behind you
