Hi Tara,
Unortunately, you are on the long list of folks who have been pool stored.
First of all, a Vinyl pool does not need a required calcium content. Its important for plaster ones. So, let that problem go. Your CH is just fine where it is now.
Next, I recommend get your own quality and repeatable test kit and stay away from the pool store from now on, as well as low quality test kits that are not repeatable.
Most of us here on TFP use the TF100 test kit. Only available online at
TFTestkits.net
Without a good test kit, there isnt any way to ever be in control of your pool, and know what it needs. TFP only advocates what your pool needs, and not what someone at a pool store wants to sell you (whether you need it or not).
Like woody mentions, click on the Pool School button, and start with filling out your signature, because we will need your pool specifics to answer many of your questions.
After that, start reading the ABCs of pool chemistry. I will shed a lot of light on some things for you.
And here are some references for you.

SO we had an AGP put in about 6 weeks ago. We are complete;y new to this whole thing. I had the water tested at the pool store and they told me the calcium hardiness was 240. At their direction, I have now put about 25lbs of calcium in the water. With that said after shocking the pool last night, I have found that the Calcium hardiness is now even higher then it was when I first started this process! I am getting extremely frustrated(and going broke buying these chemicals!). Now I know that shocking the pool can raise the calcium, but does that mean that I have to start all over again and the calcium will not go back down? Also I cannot get my chlorine under control. The level is either too high or two low and there is never an ideal range. I have two 3" tabs floating in the pool at all times but to no avail, it continues to be under chlorinated unless I shock it. I am so confused with all this information and continue to get different info from the pool store and online! Please someone HEEEELLLPPP!!! Thank you!
