You won't lose anything by rooting. No information nothing! You will rather gain root access and then you can install the very best apps android has to offer!
And wipe is only required when you're switching between different custom ROMs. But even this data can be backed up using apps like Titanium Backup or by creating a full system backup through various recoveries like ClockWorkMod Recovery.
PM me if you need any help with this.
