The priority is to learn Arabic as Arabic is the language that Allah has chosen as a vehicle for His last revelation-His best gift to humanity: the Holy Quran. Therefore, your passion to learn Arabic should be more overwhelming than your zeal to learn Urdu. However, you should never have to sacrifice your Urdu. A sound knowledge of Arabic will only speed up your study of Urdu, given the fact that a large percentage of the vocabulary of good Urdu is derived from Arabic.
