To make matters worse I have two domain registrars that haven't been open, nor had support until tomorrow so our main domain (and a few others) is sitting in limbo until tomorrow morning until we can update the NS and A records.

that should happen at your DNS host, not your domain registrar.
you should be able to edit your DNS records using a web interface.
