advice for brisket on a pellet grill

I have never made a brisket before and need some advice. I will be cooking a 14 lb packer on a pit boss grill.

This is what I know so far:

• trim using Franklin's videos as a guide
• S&P rub, brine at least overnight in the fridge
• 225
• Try not to wrap to get the best bark

My questions are:

• Will I get enough smoke with just pellets?
• Do I need to add water in a pan on the grill?
• How long of a time frame am I looking at? Should I just put it on at midnight the night before to have it ready for a 6pm dinner the next day?
• Can I just wrap in foil after it's cooked for 1 hour?
• Place the brisket fat side down on the grill?

Thanks!
