1. No, just to check they all agree with what on the plate before we brief.
2. No, just manual start.
3. "OFF". SOP in my company to always do packs off take-off.
4. No hard and fast rule. Tend to switch them on with a "BRAKES HOT" ECAM caution. However, if one of us remembers and checks the wheels page we can and do put them on before any caution is given. A lot of people let the brakes cool to much which leads to too much brake wear when taxying back out again. I undertand the optimum temperature for best braking is approx 150 degrees.
Hope this helps,
