As far as your electrical goes. Dig 18'' trench, put in 2x 3/4 pvc conduits, One for electrical one for your data cable. You glue it all togeher similar to sprinkler pipe. As far as electrical goes, do what is called a multi wire branch circuit, which in your case would be 4 wires, Black, Red, White, green Black and red all 12ga, (unless your shed is really far from your house) . Put this on a dual breaker on both phases of electricity, white and neutral go to there respective locations in the panel. this gives you 2 circuits without the need for a disconnect box to be code compliant. I have run data right next to power without issue. i doubt it will be that long of a run. By running your data cable in conduit, when cat 7 comes out you can just pull the old one out and put in a new one.
