Thanks for your responses KathrynH, aeh, and NotSoGifted.

I'm going to try to get a copy of Unwritten Rules and the Skillstreaming to see where those will get us. Amazon has the Skillstreaming 3rd edition Guide for Teaching Prosocial Skills. Aeh do you think the Guide will be enough or should I get the Lessons Plans and Activities book too?

Our softball season is wrapping up so I'm just going to keep an eye on things and see how the last few games go. I gave DD10 some suggestions for the girls not throwing to her and we tried to role play a little (this was mostly amusing to her and she giggled the entire time). We will see if she is able to stick up for herself and put anything I suggested to use.

My examples above were just 2 of the more recent issues I've noticed and there is much more to it (like her baring her teeth and growling at kids when they try to tell her what to do - for instance). I want to get a better handle on this before she hits middle school and/or puberty because I'm afraid that will probably compound the problem.
