You've done a pretty good job here. You've also gotten a lot of good advice by a others too so here are my $0.02, or more.
1. I've found that AutoISO can mess things up, so the comment about not using Auto anything is spot on.
2. AF-On, use it to focus and the shutter release for the shutter only, otherwise anything crossing your field of view can throw off the focus point. It will take practice to do that with your thumb while you still shoot with your finger, but it works, especially with soccer and the players on all sorts of different focal planes.
3. Russ is right about Aperture, you really don't need to, and in most cases shouldn't, use f/2.8. Check this site to see what your DOF will be using your 300mm
Just play with this a bit and you may not have to go back very often once you get the idea of how razor thin the DOF is with your AP wide open.
I'm going to assume you were shooting quite a bit at about 60ft or 20yds away
f/2.8 at 60ft, or 20yds, you get 2ft of DOF, not much.
f/3.2 at 60ft is 2.2ft of DOF
f/4 at 60ft gives 2.8ft DOF,
f/5.6 at 60ft gives 4ft DOF
Choose your AP wisely knowing what your subject is, and also what else you will want in focus too, like opponents or not. You can see how this works with the last frame you posted, where one of your youngest daughters feet is in focus, and the other is not.
4. Just remember to be flexible and don't get locked into a particular ISO setting, AP or SS too. You don't lose quality at higher settings like 3200 or 6400 which is great. Of course for every stop smaller AP you also get 1 stop less light, and 1 stop less Shutter speed too, so going from ISO800 to ISO1600 fixes that issue. Also, LOW ISO in bright light may be required, but don't forget that you can increase AP too, since that doesn't effect DOF too much, using f/5.6 or f/8 on sunny days isn't all bad.
