Q: 1. it is unclear to me how this adapter attaches to the telescope eyepiece. Do I need anything in addition to this item?

A: The Celestron T-Ring for Nikon F-Mount Cameras changes the camera lens mount to a T-mount. This would then need an adapter on the Telescope side to change the telescope to a T-mount as well. Basically this adapter is half the picture, one needs an adapter on the telescope side as well, as most are not native T-mount.

Q: 9. Is this the adapter to mount Nikon DSLR D7000 to Celestron TrailSeeker 100 22-67x100 Spotting Scope?

A: The Celestron T-Mount SLR Camera Adapter for Nikon F-Mount needs to be connected to an actual T mount, such as https://bhpho.to/2UfejnB , the normal T-mount diameter is 1.25 of an inch, and will fit the Celestron Spotting Scope eyepiece tube instead of an "eyepiece". After connecting the Celestron adapter to a T-moun, then one would connect the Nikon D7000 to the newly assembled T-mount on the F mount adapter side. It is important to keep in mind if you replace the eyepiece with a camera the magnification of the eyepiece will be reduced to 1X. Many people today prefer to shoot a photo through the eyepeice to retain the magnification.
