Can I connect a clients iPhone to my laptop to restore it?

I recently repaired an iphone front camera in exchange for a broken 5c. the 5c's lcd is destroyed. I want to use this phone to practice certain repairs and test certain things.

1.) can i connect it to my laptop to access itunes and restore it? i can get the itunes info and phone password from the client but id like to see if i could do so without contacting them just to learn how to do so?

2.) is there a way i can mirror the phones screen onto my laptop so i can input the password from my computer since the screen is broken?

3.) are there any useful repair practices i could be doing with it even though the screens destroyed?
