Congrats on the new guitar!
You're wise to ask about humidifcation. I see so many people not give it a passing thought.
If you run heat or air conditioning, you're drying out the air, and you want to stay on top of that. The recommendation of a hygrometer cannot be overstated. If you don't know what your humidity is, you really can't properly control it. If you store the guitar in its case (again, this is recommended), get a hygrometer for the case. Having one out in the room doesn't help you a whole lot unless that's the environment the guitar will be in.
45% is ideal, and don't go below 40%. Rosewood and Sitka can be pretty forgiving, but you don't want to push it.
Enjoy!
