Redmere has worked for me at those lengths but with no intermediate connection. Iaw, use the open plates that allow you to pull the termination through the opening as I've had video problems otherwise.
The sub cable should be fine, I use tartan brand- good price and no issues. Use the same way as the reds and test everything before and after pulling!
with hdmi, and terminated wallplates, use 22ga. Hdmi ( very beefy)
