A few quick comments. You may want to raise your rear stabilizers before adjusting trailer height for hitching. Often, one has to raise the front, which would damage the rear stabilizers. In addition to a visual ckeck of pin in jaws, best practice is a pull test. After confirming visually that pin appears to be locked, raise front jacks until they just barely clear the ground. Then with trailer brakes manually applied, put TV in gear and make sure it doesn't pull free. If all is good, then fully raise the front jacks. Then remove chocks. I also test all lights before driving off.
I leave the shore power connected while hooking up as my battery is old, and the jack motor runs much better on shore power. My final steps are disconnecting shore power, stowing cord, and one final walk around checking under trailer, slides fully in, doors locked, etc.
