How many hours of play would one realistically play on week 1 to gear up in s2?

Just trying to plan my time a bit. Im not hardcore for world first or anything but I also want to make sure I keep pace with the higher end of the community so that I get invited to groups.

For week 1, how many chores would I need to do to gear up? Do you generally have an itemized list? It also affects my alt planning game play.

What would a reasonable list to be competitive?
