First, you've got more going for you than you realize if you're Canadian, as things relate to the gizmos.
I'd hate to see your post go unanswered, but I'm also not going to give you a full out answer because there are better people out there than me. I know all the lingo, and I know the answers to your questions, more or less. But IT WOULD BE A TOME to pull it all together for you in a way you could totally grasp at this point...especially if "zapper" is a new term.
Get into
Hulda Clark 's material, and you'll start to get the basics.
Scios - if Newport doesn't give you the (obligatory) quantumalliance link - I'll look for it and it will shed more light. But you might want to get your head around all that preceeded the Scio first.
OOO is simply ozonated olive oil. Pretty simple. Here's where ozoneman needs to step in. Or check out the site:

It's part of the liver flush, and incorported otherwise also.
Now that you've made it to class - ONE QUESTION AT A TIME PLEASE! ; ) You'll just find the responses more complete that way. Your questions would literally take hours to answer in full.
There's also something called Google. Wouldn't you prefer to see something more documented than opinion oriented only? It's all out there - I know it's a lot to take in, but I think most people here will feel that since they had to do their own research on this stuff, then it's also something called due diligence and that's for you to do.
Good luck. You'll pick it up in no time. Things are often less complicated than they first appear - oops frgin badboys, critters, creepers, crawlers ASIDE. I didn't "hear you say" parasites?? Now that's a complicated subject.
Why don't you introduce yourself and your situation also? Might produce more productive responses. Just a thought. It's kinda like you just walked into the classroom 20 minutes late after skipping for a week and started asking people if you can borrow paper and a pencil and give you their notes.
That said, I hope you find what you might need here or that you decide you do not need to be here. No one really wants to be here at all. But we are all pretty much our own works in progress. You're a lump of clay on a wheel. Take form and show us what you're made of as well. (Othewise, just a hunch, some might wish you'd take off.)
Really not trying to be offensive here. Just realistic. I want you (and everyone) to acquire the answers needed.
