The  earlier the better. I say eat at 4, then have the plane leave at 5. its  cheap and quiet. Plus, you can sleep! also, then when you get to  Detroit you can do things the day you get there, but if you left at say 6  at night by the time you got there you couldn't do anything once you  got there.

Everything I've read says to book at least  21 days in advance before your departure date to get the best rates but I  always book within a month.  I always use Yahoo Travel, Cheaptickets,  and Hotwire and pick out the best ittenerary with the best price.

Ideally,  you should book a flight a few months before a long haul flight or a  few months/weeks before a short haul flight. im sorry i do not know  anything about sites with airlines going to Detroit, and i dont know  where you are flying from. From the UK you could try Luton or Gatwick

It  depends on where you fly from.  Northwest has a big presence in Detroit  but I would first try Southwest Airlines or Spirit Airlines.  Hopefully  those 2 carriers fly from where you live or from an airport that is  close to where you live.  Just remember that summer is a time where it  is more expensive to fly since students are out of school and that is  when people start taking vacations.
