Your choices on reel sizes are good except i prefer 300 copper on a 55. If i had my pick i would choose the high speed Okumas all the way. It may not be as noticeable with short coppers but ts a big deal with the longer lengths. Its a lot less work. As for releases, I like Scotty planer board releases for all of my coppers. Long or short it holds them all http://scotty.com/product/no-1177-planer-board-release/). Okuma GLT or Okuma White Diamond copper rods both offer good choice for rod selection.
Excessive braid backing may not be needed but it does make it easier to spool and quick work when you are spooling a bunch of reels.
