You need nitrates below 20ppm - you'll likely need to do at least two 50% water changes to get nitrates as low as possible.

If you cycled with pure ammonia, do a 80-90% change, lower you get the nitrates before adding fish the better.

No harm in adding a large dose of ammonia to make sure you are indeed cycled. If you dose the tank and find it is all gone in 24 hours you are cycled.

There is actually nothing stopping you adding a FULL stock of fish at this point, although better to ease on the side of caution and add slowly. Usually with ammonia fishless cycles, you will create such a large amount of beneficial bacteria, it will not send the tank into a cycle if you fully stock.

Let us know how it goes.
