squale,
I would suggest pulling up all the college websites and getting the course guides and taking a look. I'm thinking community/junior colleges are more geared towards machining and 4-year schools will be focused on engineering.
Not sure if you want out of state or not, but I'm in Michigan and I've taken machining at Mott Community College. There shop is all manual machines.
I've also gone to Macomb Community College and they have a HAAS setup that sounds like the LCC one described just above. Between each school Macomb had a much better setup, but they were partnered with HAAS so it's a given.
They also have classes in ArtCAM which is how I found them. I think it really depends if your brother plans to go out of state. Or where he lives.
It's really just a matter of looking at school sites and then take a trip. Talk to previous students and the teachers etc. If he's that serious he MAY want to look into Mechanical Engineering.
As for learning you can probably find simulation software as a lot of this stuff can be self taught. Oh besides this site, there is a magazine called Digital Machinist which is pretty good.
There are also videos about machining around on the Internet as well.
