Need some advice
 

I just added my live rock and sand, and it's starting to clear up, should I be testing anything in the water other than salinity while this is all cycling, and should I do water changes during the cycling period?

You need to test for Ammonia, and Nitrite to start with and write these numbers down to keep track of them. I test the first few days to get an idea of where the numbers are at. Then you can test once or twice a week. When both these numbers are at 0, then test for Nitrate. When all three are at 0 then the tank is cycled. Then you can slowly add one fish at a time. I do not do water changes during the cylce period, but some do. If you do it will prolong the cycle though.

You really only need to test for nitrite, the rest are optional. Nitrite will start to climb in the beginning and eventually reach a high and start to drop down near the end of the cycle. Once nitrite is zero your tank is cycled.
