Visa exempt entry's are allowed, just depends how long you are going to stay in Thailand.
Yes, both of you need the COE. Here's the website, it's really pretty simple. You need to upload the documents it asks for, your hotel booking, insurance, flights, and covid test prepayment. They'll email you the COE.
I usually advocate doing the COE yourself, but if you need someone to help you process it for you I can recommend a couple companies. Take a look at the COE first though.
