IMO, the Buddhism aspect is irrelevant to learning kung fu. Forms though, in addition to giving a more productive method of general exercise, serve as catalogs for the system's techniques and methods of movement. They would no better than lifting weights and running on a treadmill without the meanings behind the movements.
There are reasons why you may not be learning the meanings yet, those reasons should be asked of your teachers though.
Good luck.
"I don't know if anyone is known with the art of "sitting on your couch" here, but in my eyes it is also to be a martial art.
It is the art of avoiding dangerous situations. It helps you to avoid a dangerous situation by not actually being there. So lets say there is a dangerous situation going on somewhere other than your couch. You are safely seated on your couch so you have in a nutshell "difused" the situation."
