Hey there!
I think it really depends on your pole space as it is now! Most of us find that dancing on a hard, slick surface (such as hardwood floor) rather than carpet to be much easier, so some people will put down something around their pole, if they can't get away from the carpet.
Though expensive, I would also seriously recommend a crash mat for your pole! This allows us to train aerial moves with peace of mind, because if we happen to lose grip, or have a bad day with our strength, or just aren't fully secure with a move yet, that crash mat may mean the difference between uncomfortable and totally injured!
Finally, of course, there are fun things you can add to your space. I would love, one day, to have cool lights in my pole space! Though not necessary, they can sort of help you to feel like your pole space is separate from the rest of your life, giving you the ability to focus and let everything else go. Other people find this simply by changing clothes and closing the door, some love to put their pole shoes on, and some of us don't even need any of this stuff to get "in the zone!"
It's all up to you... but I'd say, look into a good crash mat ;) Even if it's just for the future, a few months or even a year down the road, you'll get it and thank yourself one day for putting it down!
