You have 76 DLUs remaining which will allow you to add 19 or so phones depending on type. If you need more than that you should purchase additional licenses.

Correct in CUCM 6.1 everything was DLU driven and no distinction between was done between different levels. Simply use the built in calculator to come up with number of DLUs you need. You may not be able to purchase more DLUs as those are I belive EOS so the reseller (use Cisco partner) can convert those into UCL or CUWL licenses for you.

Also, consider upgrading as 6.1 has been EOS for some time, and will soon be no longer supported (September 30, 2013):
