I don't know the answers to your questions, but you did put this thread in the right place, so don't worry about that. A more descriptive name for the thread would've been better (e.g. "Does anyone have these mods?"), but oh well.
The 1st Class Colors patch has been dead for ages. The problem seems to be that the downloads either expired somehow or were taken down for some reason.
