What address should I use for my DTV application in Thailand?

After writing your current hotel address in the country you are applying from, it will show a box asking if it’s also your residential address , so you will choose no and put your country address in the new appearing box

Yes, your permanent address can be the same as your current address if you permanently live there; however, for a Thai E-Visa (like DTV), Permanent Address is generally your home country's registered address, while your Current Address is where you are physically staying while applying (e.g., a hotel in Laos/Cambodia/Vietnam, not Thailand). If your home country address is where you are applying from (e.g., applying from your US home), then they are the same; otherwise, use your home address for permanent and your temporary location for current.

Yes, do as you already wrote
