That is obviously a bug - I'd like a track if you could. As for the Helos attacking you can change the default behaviour of the Wingmen in the ME.

This will be fixed. It changed because hiding units broke CA missions. We are looking at a another way to Hide units in the Mission Planner and the F-10 map separately.

Ok this means the A-10 module did not install correctly, reinstall the A-10 module for DCS world, and then go to the windows start menu -> Eagle Dynamics and click repair.

A Vikhr or Hellfire is just as lethal as any other missile, of course the AI should give himself the best possible chance of evading it.
That said, you can set the AI not to react to a threat and what evasive behaviour he performs in the mission editor.

It is not possible to have the cursor fixed to the middle of the screen. The method you've highlighted above actually originated from a bug in the original Black shark - many found it useful and it was made an option.
It is an unsupported feature, sorry.
