some questions i have to improve myslef

1. When you are hunting a boar. How do you make it to where when the villagers garrison they auto shoot when they come out? I tried shift click and the tc ends up shooting the boar. What sequence of hotkeys do I need to hit to make that work?
2. How many villagers should I have on wood for making farms in feudal to castle? Will 14 villagers work enough to keep farm production going till you can castle?
3. When do I get wheelbarrow? Do you have a specific number of villagers you hit and then research? Or is it right when you hit feudal?
4. When do you get horse collar? Immediately when you feudal if you can?
5. Does patrol work or is it attack move now?

Any other suggestions would be appreciated. I went up to 1500 (1v1) and down to 1300 so I'm pretty bummed. I don't know the answer to these questions and figure maybe this would help.
