Yeah mate you don't need anything special, As far as tip guide is concerned Rollers need maintenance otherwise they sieze up, when you don't want them too.
Avoid Silicone carbide tips if you can, the chip and crack easily when you wind swivels into them.
Any old 24 kg rated rod is going to do the trick for you. have alook around for a 6 foot rod, as opposed to the more common 5 and half footers. You want a bit more clearance for the rocks, most use 7 foot plus but that makes life abit difficult for fishing off the boat. Having said that I'm using a 6 and a half footer on 24 kg for kings.
Reels don't have to be flash, I see that Gofish tackle have the old daiwa seeline 450 on there site for $250 that's as good as anything.
A dawia SL40h or sl50h will also do what you want but without harness lugs. Despite what the aficiandos say you don't have to spend much for chasing kings
