1. If you go into preferences you can change the slider at the top labeled "Message Delay" to try and make these messages last longer. Otherwise, its just a matter of trying to keep track as best you can. Stay small as you're learning and you'll get more used to it.

2. If you right click on a unit it brings up their stats and other information. You can move your cursor over any of the four weapon slots and click on them turning them red in color. You have disabled this weapon and it will not fire until you repeat the process.

3. Whether units gain any modicum of safety from riding in a vehicle is largely dependent on the vehicle's class. APC type vehicles treat riding infantry as inside, while other classes that can carry do not, sometimes having an affect on the number of casualties when a vehicle carrying units is destroyed.

4. A bug? Yes and no. Because of the limitations of the game code as I have been led to understand, a helicopter on the ground is much the same as any ground unit. If it has a clear line of sight to the target it can and will opfire its weapons at an enemy target within range. That it is a landed helicopter doesn't change anything in the opfire routine.

5. This you'll get used to as well, its something that everyone does, and after probably a good decade of playing some iteration of SP I still make this mistake.
