Hey, Shannon, Good Morning!
First of all, your knowledge of pools may well already exceed what you'll hear at the pool store. You can do this...just keep asking questions and the good folks on this forum will help....as much as you need to get your pool clear.
Right off the bat, your CYA looks pretty high and has probably been a big factor. However, the first thing we'll need is some good test results so we'll have a baseline from which to start.
Visit the pool store as soon as you can and get a set of current test results you can post up here. Ideally, you want them to give you FC, CC, TC, pH, Alk, CYA, and CH....Free chlorine, Combined Chloramines, Total Chlorine, pH, Alkalinity, CYA (also called stabilizer) and Calcium Hardness.
Get those posted up for us (don't buy anything) and we'll get that pool cleared up and you'll have gained a great understanding of your water
