There is a solution for the radio messages.
WBNN Mission Orders Lite.

This mod drastically reduces the number of radio messages you receive during the campaign to a total of just 229 which are all relevant to missions scripted into GWX or important to your decision making process (e.g. location of supply ships). WBNN is designed for GWX but will work with any mod.
