Old computer destroyed- transfer HELP

Hey all,

so, both my MacBook and my time machine backups just got destroyed by the water sprinkers coming on. All I have left is the data on my iPhone. I keep all my iPhoto, music, contacts, calandar, and bookmarks on my phone. How will I transfer them to my new computer (even if it is a paid program, I REALLY need to keep this data. Also, how will I keep my new computer from deleting everything on my phone, ESPECIALLY my text messages, when I sync it for the first time? Again, a paid program would be fine because I REALLY need to keep this data

thanks for any help you can offer, and sorry if this was hard to read (typing from my iPhone)
