If you are only in Thailand for 30 days the international drivers permit (IDP) should be enough.
Do you have the IDP?
If you are staying longer than 30 days you need a certificate of residence from immigration and medical certificate from any medical doctor, if you have the IDP you only need to do a few eyesight/reaction tests at the transport office. You also need to watch a short video and answer some questions.
Opening a bank account here is a bit of a catch 22 situation and definitely the most difficult part of the non o retirement visa process. After trying at several banks and branches of the same bank I managed to open one at Bangkok bank, but you need a letter from immigration to achieve this, if it is still possible. If not this would be worth paying an agent to arrange as I understand they charge about 3,000 baht for this service and you are not tied into anything for future years.
If you get the

day tourist visa in advance before you travel, you have plenty of time to organise everything.
I believe a 6 month lease is required to obtain the non o visa, so you can also look around for a rental place in the first 60 days of your stay. Ensure that when you rent a place the contract has a copy of the owners ID card and their "blue book" proof of ownership of the property.
yes, it's a bit silly because you know you will not use the flight. I booked the cheapest flight I could find. Since then I have seen someone post that they used Malaysian flexi flight booking, as it is fully refundable if you cancel it. They said they only lost a couple of dollars on the exchange rate. Have a look, it seems like a great option for this situation.
it is very hit and miss. It's a case of trying as many banks as you can until you find one, but if not I read it costs about 3,000 baht with an agent so if you are struggling maybe it is worth that amount.
Someone else asked a similar question and somebody suggested that Malaysia Airlines offer a flexible ticket that is fully refundable.
I would have a look to see if available, they said they have used it and lost a couple of dollars on the exchange rate refund, but otherwise sounds good for you.
