Take along an air rifle if you want. But I think it better to ask Wayne to arrange to squad you with an experienced shooter to show you the ropes and share his rifle (already set-up for FT).
Wayne has lots of contacts and resources to arrange this, so that you can learn the game while also knocking down some targets with a properly prepared airgun. Many clubs around the country prefer to do this with new shooters. (We have too may people attending their first match with an unprepared gun, who then run away disappointed, never to be seen again...)
There are many PCP rifles to buy, and an AA S500 is certainly among them. But attending a match and shooting with someone who is experienced will also expose you to other rifle options that will help you decide what you want, once you decide you're hooked on the game first.
