CMOS vs TTL power and impedance
I will answer the output impedance since that seems to be the case that you have the most problems with.
Imagine a perfect source, either ground or Vcc with a series impedance (resistor). The current and voltage is given in the spec sheet for one test case. Use this to calculate the equivalent output impedance. The value of the load resistor doesn't matter, in fact it would be an electronic load for the vendor testing.
Since min and max values are given in the spec, the impedance will have a range.
Note that for TTL, the equivalent output impedance is much different for logic high and logic low.
Note that the output impedance is an estimate, it will vary somewhat depending on the load condition.
And I agree with what Elliot commented, look at your class notes, your instructor may want you to do this a different way.
