Good and clear comment, but he still wanted a Non-O visa based on marriage to a Thai national. He just got a bit unsure about the financial requirements and thought it required both income and a lump sum.
It’s just your friend Stuart who’s got things a bit mixed up and is talking about an extension of stay in Thailand.
You can apply for a Non-O, as you’re trying to do, by providing documentation of at least three months of income of a minimum of 40,000 baht per month.
400,000 baht is just an alternative basis for applying if you’re not using income.
You cannot apply for two visas at the same time if the application isn’t approved or denied before you travel. If you hold a passport from the list of 93 nations eligible for a 60-day visa-exempt stay you can first enter Thailand under the visa exemption and activate your visa later by a border run once it has been issued.
If your visa application is denied, the alternative is to use land transport companies to make border crossings in order to obtain new visa exemptions.
