It seems you're trying to tightly couple Skywarn with your RACES program, which I suggest is a pretty bad idea.
The Skywarn program here in Wayne County is managed, along with ARES, under our RACES organization. To be a part of RACES we require a lot of the requirements you ask for, including the ICS courses, but certainly not to be a spotter.
The NWS only provides training for severe weather because that's all they care about, I'm sure if you go to the training and call your NWS office with a report, they'll take it. If you're trying to manage the amateur radio portion of it, to tie in with your ARES/RACES, that's fine, but just make sure people are educated that it's not a requirement of actually calling in a report.
He he gotta make the disclamer that this is not mine in any way. I'm in Tennessee and the program I work for is under the FireCorp program with the local FD and funded by the city. I saw this at the conference when I went up there.
