Did you buy it new? if so will be factory waxed and you won't do better than factory. if you bought used then yes give it a wax. Either way you'll need the gear soon enough. One thing I would say is don't worry about a specific waxing iron. a cheap non steam iron will be fine. I have a temp adjustable tefal non steam iron that is great and was less than £20(FS2620 1200 Watt Dry Iron but any non steam iron is ok). flat base no holes for steam is key I recently bought Xcman Nordic brush kit from Amazon. Much nicer brushes than ones in a one stop shop kit I've had for years. you'll need a perspex scraper too. You'll want an edge tuner sooner or later but can wait if you bought new.
