Dry hopping aside, you bottle once the gravity has stabilized and the beer tasted good. Take gravity readings 3 days apart to confirm it is safe to bottle. Once you know it is safe, give the beer a taste to see if it is wise to bottle. If it doesn't taste like flat beer (eg has any off flavors or aromas) just leave it alone for a few days and taste again.
Airlock activity is NOT how to determine if the beer is finished.
Most importantly, relax, and don't try to rush it. I know your are excited with your first batch, but nothing good ever comes from rushing a beer. You just need to accept that brewing happens on the yeast's schedule, not yours (and certainly not the timeline of the kit instructions.)
" i plan on adding a half vile of yeast and priming sugar of course when I go to bottle
"
You do not need to add any yeast when you bottle. There is plenty of yeast in suspension to do the job. Adding more is just going to get you more sludge in the bottom of the bottle.
