As far as long toss goes I'd recommend following the approach from this link:
long tossYou'll note that there isn't a station 1. Station 1 is running about a 1/4 mile.
For station 6 I'd recommend that you throw football passes (with a baseball) to the kids to get them to accelerate to the ball. I also have them go out looking over one shoulder and throw to them over the other shoulder and also have them go out straight away from me, throw the ball straight over their head, call out ball! and then they have to find the ball and catch it. This gets in both running and outfield drills at the same time.
We also work in wind sprints on occasion and since you probably have yard lines on the field you can have them sprint back and forth at about 10 or 20 yard intervals touching each 5 yard line along the way.
