1000 value you refer is the max number of client database entries 2500 can handle. Not for a single AP.
200 value is per radio/per AP max number of clients and not controller specific. Again this value is theoratical max & you should not have that many clients per AP. Practicaly 25 max per AP is good guideline.
You do not want to have any other licence other than number of AP you want to support by this WLC.
Hope this clears your query
