Numbered t-bar anchor tags run from $50-$70 for 100 tags.  The tagging guns are about $25.

Not so sure about the tags but for the bluegill part yes. It will hurt your pond but it wont destroy it, just assuming that you have more then 1 baitfish in there for those bass to feed on.

6-7lbs average can I come fish with ya. lol

what I do in my pond is I cut off a part of there tail it wont tell me the date or what I caught it on but it will tell how many fish you got in your pond.

Tags are a great idea, and keeping some of the gills won't hurt the lake at all. It is good to have small bass in the lake to. They are the next generation, but make sure there is not to many. They can keep the big ones from getting bigger by eating most of the food. I am not sure what the formula. I am sure that ouachitabassangler knows more about it than I do. He used to do that stuff for a living so he will be a great help for ya.
