Can't help you with airport transport options as it's been 10 years since I was last there, but I do recall sufficient English signage to get around and not get into trouble. We were there for 10 days and roamed around quite extensively, and I don't remember language or understanding ever really being an issue for us. We enjoyed our stay there very much, and I hope to get the opportunity to pop there again with work sometime in the not too distant future.
I'm sure some nice people with more recent knowledge will be along soon.
Happy travels.
