What are the application procedures and reporting requirements for a Thai Spouse Visa extension?

Questions on Thai Spouse Visa & Extension + 90 days report

I got my 90 days single entry Non-OA visa based on spouse outside of Thailand, from what I went through the previous posts under the extension topic I can apply a 60 days extension by using the reason of visiting family for ONCE. so my questions as below

1.1 When should I apply the 60 days extension? Is it the soonest I can apply is when my current visa has 45 days left? The total date will be 150 days of stay from the date I entered Thailand, is that correct?

1.2 Do I need to do TM47 90 days report when I apply for the extension (60 days, visiting family) in a province immigration office

2.1 Do I need to do TM30 report within 24 hours arriving home in my local province immigration office after leaving 14 days ASQ in a hotel located Bangkok?

2.2 If I stay in Bangkok (rented condo) for a couple days before returning home and do not file TM30 until arriving home (province), will that an issue for me when I report TM30 in the province immigration service?

Look forward to all expertise advices and appreciate for the helpful posts in the past.
