Do my husband and I both need 800,000 baht in the bank to stay in Thailand on a Non-Immigrant Type O-A visa?

Okay, your easiest choice by far would be to BOTH get Non-Immigrant Type O-A visas from a thai consulate in your country BEFORE you wing your way here. <- That is the easiest and least troublesome way to both get almost 2 years of stay in thailand.

The other choice is for your husband to get a 90 day Non-immigrant Type O visa then apply for a yearly extension of stay based on being over 50 by meeting the financial requirements. AND you to get a 90 day Non-Immigrant Type O visa based on being the spouse of someone on a long term extension of stay THEN get a matching yearly extension without the need to show proof of funds.

Your extension would be 'piggy backed' under the "trailing spouse: clause.

While your husband could get a 90 Non-O visa inside the country from the immigration office from a tourist visa or a 30 day visa exempt entry stamp you could not and would have to get your 90 day Non-O visa from a thai consulate in another country. (Non-O visas are not issued in country for trailing spouses of people on retirement extensions)

Sorry I deleted your other post. There was some good information in it, but there was also some total crap and I couldn't be bothered to sort thru it ..

Good Luck

I deleted the other thread because of all the b/s posts :O there was NO way I could clean it up to the degree that it'd make any sense.
