If it's your first time with this bike, I'd say get the seals and bushing up front.
The '84 has and extra set of bushings.
Look at the fiche and make sure you have the needed o-rings. Some, like #61, you have to get from Honda. I think, no matter how carefully you plan, you always end up needing to run to a parts store for an o-ring or washer.
The list I came up with:
#68x2 top bolt o-ring
#65x4 air crossover o-rings
#39x2 Fork seal set
#15x2 backup ring
#16x2 guide bushing
#17x4 slider bush
#60x2 special washer
#69x2 (I think this is the anti-dive housing molded o-ring)
#66 should also be on the list but isn't available. 37.5x2mm o-ring. I think this is a JIS S38 o-ring.
