I am going to take out my first, newly built AR15 to the range this weekend and need help zeroing it.

I bought these sights from MidwayUSA.  First thing I discovered that when the aperture line is lined up with the line on the rear sight, it is not an exact middle.  I confirmed that by counting all the clicks from left to right and then counting back half way.  Should I use the "half-way" method or line up the lines?

I found these targets for zeroing in.  If my barrel is 18" long, should I use the target for 20" or the one for shorter rifles?

When I am zeroing in for 100 yards using this target, do I aim at  the center of the silhouette and want the grouping to be in the middle of the circle (lower then center mass)?

Yes.  Don't overthink this.  
Try shooting it actually at 100 after that.

Continue to keep aiming at the same point. And most sights you are moving the point of impact

I am not sure I follow the previous 2 responses.  I get that I have to shoot 3 round tight groups and move the group into the bulls eye.  At 25 yards, is my POA is supposed to be POI?

Point of aim is the BOLD CENTER LINE adjust sights until point of impact is the small circle below bold center line. I would then shoot at 100M to comfirm 100m zero. I have used these targets and they are on the money.

Perfect!  That's what I needed to hear.  Thanks.
