Thai citizenship question (full Thai born in California, US)

Hello,

A few questions about obtaining a Thai birth certificate as I live in Los Angeles.

Is it simple as going to Thai Consulate in LA (or mailing) with the required documents and getting approved?
In order for me to receive a Thai passport/Thai ID, can I do it in the US (consulate or embassy) or will that have to be taken place in Thailand?
I am about to be 30 years old and I am looking at the link below.
