Sounds like you have a good handle on what should be done, Coupe. And really you didn't make any big mistakes in the original stocking, at least nothing that can't corrected. Ratio of 18 to 1 BG to LMB is pretty good, after all.
Re the CC, are they able to spawn in your pond? Do you see small ones? If not, that will make it much easier to reduce their numbers. From what I've heard, though, CC are plenty smart and very hard to fool after they've been caught, so you might consider taking out every one you catch.
By the way, does Louisiana allow tilapia in a private pond? They could help keep down FA and feed the LMB at the same time, especially when the temps get cool and they become sluggish.
