I would say for right now, don't worry about all the other numbers, let's just concentrate on getting the pool cleared up. First off, when you say you added "pool shock" this morning, what were the ingredients? Second, here's a link to the method for estimating your chlorine levels with the OTO kit. http://www.poolforum.com/pf2/showthr...a-good-testkit)
I wouldn't worry for now about any of the other tests except for chlorine (you don't have bromine in your pool, so ignore that reading altogether). Wait an hour or so after you add chlorine to retest, and make sure you're taking your water sample from under water--take your collection container, turn it upside-down, then push it as far underwater as you can before turning it upright, so you're not getting your sample from the surface. Keep your chlorine as consistently as you can at 12-15 ppm, with the filter running.

I also would recommend that you take a sample of your pool water into the pool store to have it checked for metals--but don't buy any of the stuff that they'll want to sell you, except maybe some metal sequestrant, and only IF the water tests positive for iron/copper.
