I'm not sure if "Lets go shore dive'n" is still in print. It used to be on the web for free but the link's dead these days. It still might be available in print.
I see mentions of rock entries in Kona, but frankly they're just not that bad. Compared to the rock entries we did back on the Oregon coast they're a piece of cake. You can go to the Place of Refuge, walk across 120 feet or so of flat lava, find the entry, sit down and gear up and do 1 step and you're in 4-6 feet of water in actual reef... fish right there...two kicks and you're out of other peoples way and diving, nothing could be easier in my mind. Other entries will be more "difficult" but compared to walking out on sand and having to kick quite a ways to see anything (sand usually equates to few fish), it's not really all that difficult as long as you avoid getting in where it's facing the swell.
Shorediving.com is still a pretty good reference, no maps though. The shops are usually pretty good for info on entry points and such.
