Looks like you are doing OK.
Gravity: Apple juice is probably about 1.046. Added sugar will add about 24 points, or 8 per gallon to give you an estimate of 1.054. If it ferments out to 1.000, should give about 7% abv.
You didn't say if it was clear or cloudy juice. If cloudy, you could be looking at 6 months or more to clear unless you use pectic enzyme.
If clear juice, leave where it is for a month, then rack and leave for at least a month, preferably 2.
If you like dry cider (I do), just prime like beer. I like to use 1 cup of apple juice per gallon. If you like it sweet, it gets more complicated; read other threads for advice.
