How to sync iphone to two computers

I use my desktop Mac Pro and its iTunes and iPhoto to do all of my music purchases, iphone games and apps purchases and manage my photos, and have my iphone synched to it, but I am going travelling and will be taking my MBP laptop.
My laptop iTunes/iPhoto has none of my music, iphone games and apps or photos on it so I know that if I connect the iphone to it and try to sync it, it won't work.

I would like to have all of the same music, photos and purchased games moved over to my laptop so that I can use it to keep my iphone synched and also be able to buy additional games and music and be able to update iphone games and apps while I am travelling.

Can anyone please advise me on how to go about getting the same stuff on my laptop so that I can use it to keep my iphone synched while I am travelling?

Thanks for any advice.

If your phone is jailbroken you can sync two different music or photo libraries. It's easy.

It's not.
