Yeah, sounds better

You better have all the papers and copies in hand when you cross at Hat Yai. I was there, the Thai immigration lady said 'you can get re-entry permit, you need to make a photo copy,etc.' I asked How can I make a photocopy here?, she said to take a motorcycle taxi. I spoke to a moto guy, 'Hey I need a copy.' - He said 'Copy?' with tea sipping hand movement. My heart was too broken and dumped the idea.

I heard that I can't do re-entry permits on domestic flights (Don Mueang). Is this true? --> true.

i was asked to provide rental agreement from my landlord and the landlord's ID copy for tourist visa.

I went there once to get a tourist visa. I was asked to provide flat OWNER's ID copy in addition to rental agreement. All that is a troublesome so I booked a hostel on booking.com and cancelled later. FYI, they asked every single thing listed as requirements.

Hope it works.

Thai lion air. Select the payment method as 'pay at 7-11'. You get payment sheet to go with to 7-11 by certain time. If you don't go by the time, reservation is canceled.

You better have everything scanned and stored on the computer. It's gonna get busy! Hope it works well for you too :)

did you create an account here?

Upload it. If unacceptable, the system tells you to what to do. I never get rejected or failed. Next day, I hear to come to the place physically with the uploaded documents. I submit and following day, I get the passport back.
