How long have they had the rooster?
Tail feathers can look beat up if they are rubbing against something while roosting and/or just on wire. (like perches close to a wall)
When you make your next trip, get some more photos.
The supplies you have planned to take sound good. Hope all goes well!
Likely surgical removal of the bumblefoot isn't necessary. I would first try this. https://www.tillysnest.com/2015/12/non-surgical-bumblefoot-treatment-html/
Toes are crooked, more than likely she hatched that way - both feet = genetics, incubation issues, etc. I would not try to correct...
