So my cycle seems to have stalled at high nitrates. Help please? :D

The fact that you have any ammonia and nitrite is a bit of a concern. Essentially, your nitrates are the last stage in your nutrient cycle (not to be confused with your tank cycling). You need to look at what nutrients are going into, or are already in your tank. Perhaps over feeding? Perhaps insufficient water changes? How big and how often are you doing water changes into what size of a tank?
