Answer 1

check if jquery is conflicting with prototype as this is a problem when all prototype functions doesnt work

use noConflict for that

Good news getting jQuery included in magento 2.0 :)

Answer 2

I have dealt couple of times with such a problem and nine out of ten times it is caused by a misbehaving shipping or payment module. I suggest you to disable all non-default modules and retry and see what happens.

I would try this after you have walked through default Magento debugging procedure.
