What are the steps and requirements for a NON-O married visa extension in Thailand?

Well i spent half a day at CM immigration yesterday knocking my non-o married visa extension application into shape.. my initial 90-day non-o expires 4-Sep so wanted to get in early and iron out any wrinkles.. was well prepared and thought i had my act together.. until i realised i hadn't printed the photos from my phone before going.. but wasnt a problem because got them sorted at the kiosk next to the TM30 hut at the back of the building.. and they accepted the 'pictures' printed on copy paper rather than photo paper which also saved some money.. however i did discover that a photocopy of the residence certificate from the local Amphur is not acceptable.. it must be an original, ie containing the official blue stamp of the Amphur, or immigration will reject it.. despite the fact they took the exact same original document from me just a couple of months ago.. yawn.. this document has a name I cant pronounce let alone write, but has the number 22 stamped in the corner.. so this meant visiting the Amphur to get some more originals (and numerous back-ups for the next few applications) and returning to immigration today.. at least the documentatuon had been thoroughly inspected and effectively pre-vetted ready for today.. and not by the volunteers that used to sit at tables at the front of the main building.. but by a team of immigration officials in a newly constructed kiosk which now sits in the same place.. we were told it would be fast-tracked upon returning today.. so no queuing up and waiting to be seen, just appear at the window and deposit the documents in the pre-agreed format into the basket for priority advancement into the building.. all looked to be working as advised today until the checker insisted i added photocopies of my earlier passport stamps to the batch.. the latest page showing the 90-day approval etc being insufficient for his liking.. contradictory to yesterday's advice but followed to the letter and eventually allowed to go inside to the 'family thai' booth.. again without waiting for queue number to be called.. they took and checked documentation on the spot.. and promptly informed me that black pen was unacceptable and the application form and other declarations had to be in blue ink.. having never been pulled up on this previously after several visits to immigration in the last 12-months i was surprised to find this suddenly enforced.. especially as the pre-checking had not identified this as an issue.. at least the officer did agree to transpose everything to a fresh form later if i was willing to sign it in blue now (fantastic) and apart from asking us where we met and how long ago, had no other queries.. when i asked about applying for the multiple entry 're-entry' permit (ie. 12-month permit) she told me i had to wait 1-month before i could do it, which seemed odd at first.. until she explained the first month is an 'under consideration' period and i had to return to get the full 12-month married visa stamped in my passport.. so they have only extended my current visa's expiry date by 1-month today.. although i was assured no queuing and no further payment was needed when i return on 4 October.. though i need to be available during the intervening period to take phone calls from immigration should they wish to query anything.. or indeed to make a home visit, although this wasn't mentioned specifically.. so all done for now and I'm in the home straight.. but sharing my experience here so other peeps can benefit from the knowledge i gained and maybe avoid some of my goofs.. so as to make their own process a little easier.. amen! Ps. They also put a note in my passport with the date my first '90-day' report falls due and explained i can do it up to 14-days early.. and indicated that i can do it online despite being my very first report of this kind.. which i immediately queried and sought clarification on.. so I'll have to wait and see if the system allows it when the time comes!
