OP, I know that being the parent of a HS junior is stressful -- I have been through this more than once -- , but I would strongly suggest that rather than thinking about application strategy at this point, you focus on making your home a place where your child can get away from the stress of junior year. As a parent and as a former college admissions staffer, I would say that you really don't need to come up with a plan on whether and where your child will apply early until late next summer/early fall.
Moreover, the information you're seeking is not likely to be very helpful in developing a plan. Knowing scores and GPA alone will not help you in assessing your own child's prospects without knowing much more about previous applicants/current students, including where the applicant attended high school, what kinds of activities s/he was involved in outside of school, whether s/he was a recruited athlete, legacy, or URM, etc.
It may, however, be useful for you to spend some time learning about how early application programs work in gneral . In this vein, I'd note that previous posts have been a little confusing. To clarify, while early decision programs are always binding, early action is non-binding --so the student has the option to apply to other schools in the regular decision round. It's important to note, however, that some early action programs are exclusive or single-choice and do not allow the student to apply early to another school, while others do.
