what @blossom says.
Be sure the schools you visit are not just reach schools. This was my biggest regrets when we started visiting. Much more important to focus on the realistic ones than the ones that there is a 10% chance she can get into.
This isn’t so much about this summer, but try hard to plan your visits for when schools are in session. I wish I could remember what CC’er to attribute the following quote to, but I love it: “Visiting a school when the students aren’t around is like visiting a zoo with no animals” 
The FAFSA EFC should be viewed as the MINIMUM you will be paying for college. If your FAFSA EFC is $0 when your daughter actually enroll a in two years…she would get the full Pell Grant, and a $5500 Dorect loan guarantees…and possibly SEOG and state aid for low income students if your state has that.
The NPC gives you an estimate of what you might be paying at a specific college. Because MOST colleges do not meet full need, it is likely that your net cost will be higher than $0 at any school that doesn’t meet full need. The NOC really should be what you look at. It estimates your net cost at each school…and you will see…this will vary substantially from school to school.
The current net price calculator is set for students enrolling in fall 2016. Your daughter won’t enroll until 2018. Need based and merit awarding policies DO change at colleges. You will need to do the NPC at the end of the summer of your daughter’s senior year of HS. Usually by September of the senior year, the NPCs are reset for current seniors.
One missing thing from your list…if you have financial considerations (and with a $0 EFC you likely do), please have a money talk with your daughter. Let her know what you can and can’t do to pay for college. It may be a talk you want to avoid…but better she know sooner than later what your net cost needs to be for her to actually attend a college. Sadly, we read of kids here every year who applied to colleges…and none are affordable at the end.
Make sure you pick tow realistic safety schools…and do that first. These would be schools at which your kid is pretty guaranteed to be accepted, that will be affordable, and that she would be happy to attend. Find two…first. It’s easy to pick reach schools. Build your list from the bottom up.
Personal anecdote. We did this…chose safety schools first. My kid actually liked three safeties better than any other colleges we visited. Those were her top three application choices…and she matriculated and graduated from one.
Make sure she is volunteering at a hospital to make sure she likes nursing.
The kid needs to relax, sleep in, and spend time with her friends. Free summers will not last forever, she be sorry later for wasting them worrying about things.
In fact, I’ll say that one of the three best bits of advice on the process I learned here at CC is that your college visit list needs to focus on potential safety schools, because your child’s safeties needs to be not just schools she could get into (and that you could afford) easily, but also that she would love going to. A safety isn’t really a meaningful safety if she has to hold her nose as she accepts the offer.
