SINP nominee filing for PR - How to respond these questions?

Hello everyone,

My daughter turned 22 last October, few months before her SK nomination; still they nominate her as family member under my own application (NOC7272), instructing her to apply to CIC for her own visa:
1 - What type of visa would that be? No job offer, no school application... perhaps as an accompanying family member? Open study permit? The fact that she is a nominee its enough reason to receive her visa?

2 - This month she managed to become a college student. Does she automatic revert to the dependent child condition considering all other required steps remain the same? If so, on the form IMM0008 (PR) page 2; can I list her as my dependent?

3 - Education, my wife lost her high school diploma and the school no longer exists, we tried but there is no official records anywhere (she is 48yo) Does it affect her application regarding receiving a PR?

4 – This question is regarding to TWP.
The province issued a letter to apply for a TWP which I intend to do. Again, regarding to my daughter; considering that TWP application is just to gain time while CIC does background etc., I wonder if she could also come with us so she can find and apply for a college there. Bearing in mind that she is also a nominee, does she stand a chance applying for her TWP?

I am sorry for all those questions but I felt they matter for many of us as package instead in separate.

Allow me to thank you ahead for your responses.
