Congratulations on your first test!

You should bring your PH down into the 7.4 to 7.6 range with muriatic acid or dry acid. That will also bring your TA down somewhat. Once you have your PH in range you should recheck the TA and see if you need to adjust that as well.

Your CYA level is low. I would bring it up to at least 30.

If you have a vinyl liner you don't need to worry about your CH level. For a plaster pool the CH level is important and should be between 200 and 400.
