I am wanting to flash nouget onto my device, and at the time this has no documentation about doing so. What should I do to make sure I don't screw my phone and root status up? (I am not near an expert, obviously, but I like learning :P)
ROMs are not universal - you can't just flash one from another device and call it a day.
No one has ported N for S7 yet, and due to the locked-down bootloader on the Snapdragon version / development difficulty for the Exynos version, there likely won't be any until the official one drops.
