You need to cancel your retirement visa, leave the country and get a non-b return and obtain your work permit. The company you will be working for should provide all the necessary paperwork for both the Non-B and the work permit. I would keep your retirement active until you have all the paperwork for your non-b then cancel it and go to an embassy in a neighbouring country
when you can barely put together intelligible sentences and clearly can't discern the difference between you're and your, you should refrain from calling people dumb...
You'll need a TM.7, STM.2, Acknowledgement of fines for. A Passport photo, copy of bio page, copy of your visa stamp page, and possibly a copy of your TM.30 receipt (best to take it just in case and your hotel will provide that one)
You can print, fill in the forms before you come, just leave the date blank and fill in the date when you go to immigration. Personally though, I would suggest applying for the 60 day TR visa from your local Thai embassy.
it's hit and miss. I took a friend a few weeks back and the person who was checking his documents didn't want the TM.30 but the lady next to her asked the person she was checking for a copy of the TM.30 and sent him away as he didn't have it.
TM.7, STM.2 and acknowledgement of fines. Copy of your bio page and a copy of your entry stamp, a recent picture too for the TM.7, you may or may not be asked for a copy of your TM.30 so take it just incase along with 1900 baht.
I suggest either going for 8.30am and walking through
