Steven,
The book "Civil War Pensacola" by Virginia Parks includes a full list of the units of Bragg's Army of Pensacola.
I don't know if the book is still in print, but it used to be sold at the bookstores at Fort Pickens and Fort Barrancas.
There also is a great deal of material on the Battle of Santa Rosa Island in the Official Records set.
Best,
Dale
