Go along on your own unannounced one day and see what you think. You may not like the 'feel' of the club or the training.
Have you a BAGSD branch near you? And have you looked to see if there is a Schutzhund group you can get to? How about looking up nearby trainers to see if any have done, or do, WT?
Don't go to a club simply because it's the only one you can get to, or the most convenient to get to. I am sure other people as well as myself, will back that up with their experiences.
Have you looked to see if there are any Working Trials in your area? Go along to look if you can.
With regard to showing, Companion shows [used to be called Exemption shows] are a fun way to get experience and usually benefit a charity as well. They are informal but almost always have people who show "properly" as competitors or organisers. Great for getting Nando used to the whole idea of being in a ring with other dogs, and getting you used to moving out with your dog in a ring - I was petrified the first time I was asked to do a triangle with my dog, last year - but better there than in a more competitive atmosphere.
As it turned out we didn't do so badly because I had been to a few 'proper' shows and watched what was done, so I tried to copy what I'd seen, and we'd done some garden practice as well. In fact one lady turned to me afterwards and said "Your girl moves really well" and that meant more to me than the Best Veteran rosette and cup we took home... because it meant my inexperienced handling had still allowed her to show herself to advantage... gave me a huge glow of pride :)
