That depends. What exactly are you trying to do? What is your goal? Rue is a banisher or a jinx-breaker, Fear Not (to walk over evil, I think you mean?) keeps others from jinxing your foottracks and keeps you safe from tricks others have laid for you, Fiery Wall is for protection, Stop Gossip...well, you know, stops gossiping

And St. Florian, if I remember right, is the patron saint of firefighters. So...are you trying to keep a firefighter from gossiping about people laying tricks for you, this combination might be right up your alley!

Seriously, the answer to your question is "It depends on what your true goal is." My experience is is that if I try to put too many goals into one magickal working, the Universe is like "Woman, you need to make up your mind, you want 50 things at once!"
