I think you are good to go as long as you have worms and mycorrhizal fungi. Plenty of SOM to have locked up even maybe too much nitrogen, but as the SOM gets digested by the soil biota, it will become available for the plants in a process called mineralization. The key here for you is to give the soil microbes and worms a chance to catch up. Something like this might help:
Mycogrow
ps. The Haney test gives you a better idea of exactly how much nitrogen will be released due to biological activity. I am just making an educated guess since the type of soil test you got was designed for standard NPK fertilizers, not organic biological based fertility.
