Dunno anything about NetBoot options, sounds cool when others talk about it though, hoping they'll chime in. That's for search and another thread if you can't find the info posted here already, methinks.
It seems to me that the SCSI controllers may not have been definitively identified as the culprit. SCSI Voodoo is still a possibility. Booting from a Disk Tools floppy, CD, Zip or one of Dougg3's ROM SIMMs (duno if that's an option or not) could narrow your chicken/egg problem down a bit.
I'm sleepy, a troubleshooting review of what you've tried in an ordered outline/checklist might shake something loose a/o garner more responses. Going back to basics can't hurt, you've checked the Service Source?
Sillly, sleepy question: you've reseated the RAM SIMMS? If not, definitely do, if so, do it again and clean the contacts with an eraser while you're at it.
