From Wuhan Tianhe Airport to Hankou Railway Station

Arriving by air 14.40, leaving by train 17.39. What is the best (cheap but without stress - we don't speak Chinese but I have Station address written down)? I see the Hankou Shuttle Bus - just outside arrivals - is it marked in English? How long would it take and which stop would Hankou Train Station be? Maybe, being 2 persons, would be better to take a taxi. In this case what is the price from Hankou Train Station do Tianhe Airport? - Thank you. For us is very important to catch the train at 17.39 to Ychang in order to get on the Yangtze Boat.
