I'm sorry if I'm missing something obvious that I should already know.
There's nothing you should already know, but you should be able to look up that information by yourself. Installation and distribution are far beyond the scope of this mailing-list dedicated to LuaTeX developers (and there is a user list, see http://tug.org/mailman/listinfo/luatex).
I was going to try to help with development -- at the very least by filing useful, detailed bug reports but probably by fixing stuff too -- (since I love TeX and have used C++ since before it was called that) but I had no idea that it would be so incredibly complicated just to install a current build in order to make a useful contribution. I'll go away now. I apologize for interrupting. Doc -- Web: http://www.sff.net/people/N7DR
