a pengiun 330 will do really well. i use it in my 55gal and it rocks. very good flow. but it is important to clean the filters once a week. just spray them clean try not to rub too much or you will break down the floss material. replace filters at least once a month to change the carbon and that should work for you. the bio wheels will definitely help with your bio filtration but can be kind of noisy.
