Little hesitant to worship chaitanya mahaprabhu...please help!

hare krishna,

I have a little difficulty worshipping chaitanya mahaprabhu. I want to serve the lord in his form as krishna and mother radharani. I feel that if we worship chaitanya mahaprabhu we may go to Gaura Dham in the spiritual world rather than go to goloka vrindavan. Though chaitanya mahaprabhu is both radha and krishna combined i still want to worship krishna in his original form. Can i pray to chaitanya mahaprabhu to attain radha and krishna. i wonder how the gosvamis of vrindavan were attached both to chaitanya mahaprabhu and radha krishna. what was their destination in the spiritual world?. where did they go? Please help me clear this doubt
