If a throw by a fielder hits a runner, even if the throw looks to be a good one (ie not in the dirt hitting the runner's foot, etc), it is an error if in the scorekeepers judgement the runner would have been out had the ball not hit the runner.
Unnecessary throw to a base that results in a runner advance, I assume this would apply in say a 3-1 count on a batter, strike two is pitched and the catcher throws down to an unoccupied first base resulting in "ball four". It would be E2, not BB.
Runner advancing and a throw by any fielder to the base where there are two fielders there to catch the ball and neither make the catch for whatever reason, confusion, missed the ball - it is an error on the fielder who is supposed to receive the throw. Again, IF a clean catch would have got the runner out.
An infielder who fields a ground ball and neglects to step her base on a force out, doesn't matter if she is looking to throw to another base and doesn't, it is an error if she could have got the runner out. And a fielder who receives a throw and then they step on the base and should have tagged the runner out and doesn't, it's an error.
On the pitching, I always thought the starting pitcher of record who left the game with their team ahead and they stay ahead is the winning pitcher. I was wrong and it doesn't have to be a 5-inning mercy - in tournaments there are time limits and I assume those same rules apply. But, what if it is a 4-inning game, etc.. I guess they would have to pitch at least two then.?. Also, if more than one relief pitcher is used and the starting pitcher has not pitched the required # of innings, the rules say to give the win to the relief pitcher who was most effective (this of course applies only if the team is ahead when the starter is relieved and stays ahead the entire game).
Scorekeeping isn't easy, I've been doing it for years - somethings wrong, so just keep asking questions
