A re-entry permit won't give you more time on the visa you come in on so if you come in on the 60 day tourist visa, get the 30 day stamp, and then get a re-entry permit when you come back you'd get the same expiration date as you had on that 30 day extension <- it doesn't add time to your stamp to have a re-entry
Just max out the time you're going to stay here on that tourist visa entry before you leave and then get another tourist visa from the thai consulate in Manila
