Any suggestions of the best way to arrange for a taxi or song tao to pick me up in my moo bahn near Kad Farang and take me to the airport. The phone number of a taxi driver who can understand English would be very helpful.

You could try this service, found it on TripAdvisor. Advertises 250 thb each way to/from airport/downtown and speaks English, according to the website. Phone number on the website, probably need to negotiate a rate from Kad Farang. (Disclaimer: I have no personal or professional interest in this company.)

just take Yellow Songtaew and get off at AP Plaza. Never seen fewer than five reds waiting there on the North side of the mall if you can't walk the 1 km to the terminal.

Go to the airport taxi desk with a time and date for the pick up....they with assign a cab and give you a phone number for the driver.....draw a map if not easy to find.....I lived in that area and did it that way.....250B was the fixed rate....if the driver is good get a card and use them frequently.....tip nicely if luggage handling is needed - they will remember you.....
