Absolutely all of these things are important. Not only to stopping bleeding (which is the first step) but to getting your health back.
Note: I feel that zappers are good for killing bacteria, but for parasites herbal parasite cleanses are better. I had parasites and have tried zappers (I have two), tried humaworm and Barefoot's dewormer, and Barefoot's dewormer I found to be the best. The herbs get deeper into the intestines and the zapper affects bacteria better, both affect the entire body. So both have their place.
Another really nice product for colon health and parasites is oregano oil. I believe Barefoot has the best also, but you can draw your own conclusions from reading how he makes it.
