Sync iPhone with New Computer

I just purchased myself a new MacBook Pro Retina and I wanted to make this my main computer instead of my iMac. One concern I have is syncing my phone. I'd like to begin syncing my iPhone with iTunes on my new MacBook, but I do not want to lose anything on it. If I transfer the iTunes folder and Photo Library from my old computer to my new one, will that ensure that I don't lose anything or are there additional steps I need to take?
