I was actually navigating around FAA.gov last night in order to get
answers to questions of my own however on my CFI certificate in reads
"not valid without certificate no. xxxxxxxx", which is my ATP. To
excericse at least the commercial privelages one would need to
maintain at least a class II medical. Am I reading this correctly?

No. The FARs provide a specific exception for flight instructors. You
only need a third class medical and only then if you are acting as PIC
or are a required crewmember. You do not lose your commercial
certificate if you lose your medical. That is why they are separate
pieces of paper.
