Some general tools to have would be basic hand tools, a boxcutter/knife, some needle nose pliers, and in most cases, a staple gun with staples (figure around 500 staples (aluminum) ranging from 1/4 inch to about 3/8 inch along with a staple gun). A hand staple gun will work but a pneumatic one is definitely recommended.
Other tools you may need besides a basic tool kit maybe a staple puller, punch, rubber mallet, ball peen, and duct tape. The duct tape is used to go over all staples for added protection but is not required (it will not be visible). Lastly you will need a form of spray adhesive for vinyl.
In most cases, there is spare material that may need to be cut in order for proper fitment. Things included in removal is removing rear seats, the headliner itself, miscellaneous trim, and lots of staples from the old connection points. When installing the new top, remember to make sure to get the wrinkles out and as firmly as possible. proper fitment over the guide rings is crucial as reinstalling the rear window can become gruesome if not. It's generally advised to start the stapling in the middle and work your way to the outer portions of the top. It is also a strong idea to use the shorter staples in the middle and the longer ones on the outer edges.
