Sherry, you've got a multitude of issues with your pool water. Those metal results seem pretty high. I would give serious thought to a drain and refill at this point.

Adding the sequestrant prior to the chlorine is a good idea (mbar or other metal "specialists" can advise you better than I) but I'm not so sure that the cost and hassle of the sequestrant, all the clorox, borax, then probably having to aerate to get your Alk down will make it more cost-attractive to start with new water.

You'll have to make the decision but I think, if it were my pool, I'd make a fresh start.....you'll be swimming in a lot less time.
