He talked to her for 3-4 hours, its essentially a first date, you kiss girls on the first date. Maybe not if he wasn't "feeling it" but there's no way it would be "totally out of line". Regardless you have to set the tone here, if you talk for 3-4 hours with no body contact or flirting or kissing she's going to see him as a friend. Be a man.

As far as the phone thing I've made the mistake of waiting too long several times before I figured that out. You have to call girls, and you have to call them 2-3 days after you give them your number. You haven't built up enough interest for them to be "waiting by the phone" so to speak, they will forget you, they will think that you're just playing games, they will think you're not interested and that you're (eventually) calling because you're bored, they will find someone else. Its a huge, huge error to wait 5 days to call a girl you're interested in but haven't gone out with yet.
