First, how do I silence this warning during -c?
Just turn off that type of warnings for the given scope e.g 
{
  no warnings 'once';
  *import = coderef();
}

Or just mention it again in some way (according to perldiag).
Second, why does it let me refer to *import without declaring it first or qualifying it when use strict is in effect?
Because strict doesn't deal with globs. I think it's assumed if you're messing with globs you probably (and hopefully) know what you're doing.
