I'm a little familiar with Citico Creek, but i'm not familiar with the trails you mentioned. I would surely plan on fishing ALL the creeks
and i'd keep an eye out for bears and would carry some sort of defense against them
. i have hiked up the north and south fork of citico creek and those trails were in decent shape. I have also hiked into a few other creeks where i couldn't find the trail to save my life and had to just buskwack my way out. I don't think that area is visited as frequently as GSMNP, but there are quite a few good places to fish. Hope some of this helps.
