Question [Q] Suggested Setup for new Note N9005 - Upgrade, Root First, etc?

Am supposed to get my Note 3 late tomorrow. Ordered an Unlocked N9005 version. I presume it will not come with 4.4 but something earlier.

Based on my reading here I'm a bit confused. Do I need to make sure I root before I take any OTA update? Or take the update first? Anything I need to do or be careful not to do on first boot?

Thanks in advance...
