1964
Start with "Detective Comics (vol. 1)", just get as many you can. Then "Batman (vol. 1)", also as many as you can. Then "the Outsiders", "The Brave and the Bold (NOT Batman: The Brave and the Bold)".
When Batman was not fighting crime, he was billionaire Bruce Wayne, owner of Wayne Enterprises.
Technically, yes. Batman prefers "working" at night so he rarely is out during the day but don't forget Batman is also Bruce Wayne, who of course has to be out during the day. He will be out in costume if he is needed though.
Yes, it is called Beware The Batman and will start sometime in the year 2013 on Cartoon Network.

The day his parents were murdered
Batman
for the current arc that runs all the way to Batman Inc its Batman 655, which starts the Batman and Son arc and continues on his years long Batman story. It skips around from there, but that's your starting point. Also he did work on Batman a couple times prior to this, Batman: Gothic and Arkham Asylum.
my opinion is 40th day
