There is no need to turn Neuter off as far as I am aware.
It won't interact at all with iTunes if your on an official contract.
All that will happen is it will unpwn your phone (the initial "ipwner" button bit) and itunes will upgrade the baseband (locked).
I would leave "Neuter" on as its preferable not to flash the bootloader if you don't need to!
Rememeber all the "neuter" does is let you change the bootloader at will and unlock the baseband without the bootloader "caring". iTunes can do that anyway so it won't cause any issues!
Its like restoring 1.1.4 on a BootNeutered phone - it doesn't do anything to the restore.
But if you wanted to be extra safe you could un-neuter and relock.
