way to copy content from my iPhone to brand new Mac with blank iTunes library

Bit of background:

This time last week, I had a MacBook Air and a 6 year old desktop PC. Everything I had was on both of them, so they acted as each other's back up. This Sunday evening just gone, my PC finally died a traumatic death, and I can't even get it to boot from Safe Mode. Then on Monday while I was at work, my house was burgled, and my MacBook Air was stolen, amongst many other things. All I have now is my iPhone 4S which was with me at the time. All my music, photos, videos etc are on my iPhone, but I'm very aware that when I eventually get my replacement MacBook from our insurance company (I'm being realistic and accepting that I'll never see my stuff again), as soon as I plug my phone into a blank iTunes library, I'll lose everything that's on there. Obviously I can re-download everything I've purchased from iTunes, though it will take a VERY long time and I still won't have playlists etc, and I can probably either Dropbox or email what photos I have on there, but I have a lot of video clips from over the last few years that aren't on my camera roll - they're in the phone as proper videos, in the video player app, and I can't get Dropbox to view that location, or figure out how to email them. The videos are very important to me and I really don't want to lose them; so much so that I'm thinking of never syncing my iPhone ever again!

Basically, what I'm asking is, how can I copy everything from my iPhone into a blank iTunes library? Is it even possible?

ANY input whatsoever would be greatly appreciated - I really don't want to lose all my content over this, so please please please help if you can!

Thanks in advance
