Answer 1

You can stop 7-Zip from displaying prompts by using the -y switch. This will answer yes to all prompts. Use this only when you are confident.

Answer 2

Examining 7zip source I found hidden -ba switch that seems to do the trick. Unfortunately it is not finished. I managed to make it work with several modifications of sources but it's just a hack. If someone's interested, the option variable is called options.EnableHeaders and changes are required in CPP/7zip/UI/Console/Main.cpp file. Alternatively you can poke 7Zip's author to finish the feature in tracker. There are several requests on this and one of them is here.
