What are the requirements and procedures for applying for a Non-O dependent visa for my wife and children in Thailand?

I have a Non-immigrant B visa and a work permit. My employer will apply for the one-year extension after 45 days. I am a Canadian citizen and plan to bring my Filipino citizen wife and children here on a Non-O dependent visa which we will obtain in Thai Embassy Manila - all have Philippine passports.

Several questions re dependent visa.

Are all of my children on the visa app required to report to the Embassy when the application is filed and/or picked up or can my wife apply and pick up all on her own?

Am I required to be there?

Are we required to provide any personal financial documentation beyond the visa request, guarantee letter, and proof of employment my employer will provide? I don't see this on the list of required documents on the Manila Embassy web site. We will have all the required documentation from my employer, myself, and marriage and birth certificates.

On arrival at the Suvarnabhumi airport in Bangkok with the visas in their passports will Immigration ask to see any proof of funds?

Did I miss anything?
