Thereof, can I install my own catalytic converter in California?

The installer has confirmed the need for a replacement catalytic converter. If the OEM converter is still present, a diagnosis that it is malfunctioning is required. The vehicle is specifically included in the application list for the catalytic converter and the converter is legal for use in California.

Also, why are catalytic converters illegal in California? apparently california law has changed and now my once legal catalytic converter is now outlawed because it doesn't have an "OBD-II" mark on it. Therefore some catalytic converters which would have passed smog will no longer pass the visual inspection.

Keeping this in consideration, is it legal to install a used catalytic converter?

It's not illegal per se, but there are requirements for what kind of used converters you can use. EPA considers it a violation of the policy to install a used converter from a salvage yard or sell it for reuse unless it has been properly tested and labeled.
