I wouldn't risk a short connection with flights into/out of HKG, especially if you have a first class ticket out that doesn't have flexibility.

Either take one of the options outlined above, or if none of those are suitable, you should fly in early morning or the night before. Travelling to a hotel in Kowloon or Central is fairly quick, easy and painless... it's just a short walk from the arrivals hall to the train, then a taxi to your hotel. Easy with luggage and fairly cheap.
