You're going to need a target bigger than a single piece of paper.
For the adjustments, no one can tell you without knowing your EXACT muzzle velocity and the bullet you're using.
Use a ballistics calculator like JBM:

Frankly, and I'm being serious here, if you've never shot at 1,000 yards, you need a target that's car sized, not notebook sized.
