(written from a Production point of view)
Paramount Stage 9 is located on the Paramount Pictures lot in Hollywood, California.
Most of Phase II's sets were completed when that series gave way to production of Star Trek: The Motion Picture, at which point they were modified and expanded for use in the feature film.
In 1987, with the start of Star Trek: The Next Generation, the sets on Stage 9 underwent minor modifications, the most drastic of which being the overhaul of the engineering and main bridge sets - the latter becoming the battle bridge of the USS Enterprise-D.
With new bridge and living quarters sets being constructed on Stage 6 for season one, Stage 9 contained the Enterprise-D's engineering, sickbay, crew quarters, transporter room, shuttlebay, and corridor complex sets. Other sets include the shuttlecraft interior, Data's quarters, and the Tamarian bridge seen in the episode "Darmok", filmed on 24 July 1991 and 25 July 1991. The scenes on the Rutian plaza in the episode "The High Ground" were also filmed on stage 9 as were the scenes aboard the Talarian observation craft in the episode "Suddenly Human", filmed on 27 July 1990. Stage 9 also housed the workout room seen in episodes such as "Clues", filmed on 29 November 1990.
Over the seven season run of TNG, the sets were refined - the corridors were expanded for longer tracking shots - but remained mostly unchanged even through the production of the seventh feature, Star Trek Generations.
Consisting of four parts, the videos were shot on the night of 10 March 1988 by (at least) two fervent Star Trek fans who had broken onto the Paramount lot. Wandering through the darkened sets of Star Trek: The Next Generation (circa season one), the fans were able to light select parts of the sets, including most of the ship's display terminals and part of the warp core. Dressed in a makeshift Starfleet uniform (with white socks), one of the fans acted as the host of what was likely intended to be a homemade documentary - at one point climbing onto a sickbay biobed, then accidentally knocking it to the floor. Taking still photographs of the various "working" control panels, the fans can be heard discussing ways of removing set pieces from the stage.
According the YouTube user's description of the videos, when the fans were caught, they dropped the camcorder containing the footage and fled. 
After their use in Generations, the sets on Stage 9 underwent yet another revamp for their debut as the USS Voyager.
While retaining their general position, the Voyager interior sets were dramatically expanded, engineering gaining a large second level and sickbay expanding to include a larger doctor's office and (from the second season on) an adjoining medical lab. The corridor complex was similarly expanded.
In 1995, Voyager's sickbay was modified for use in Star Trek: First Contact and again in 1997 for Star Trek: Insurrection. The entrance to main engineering also represented the USS Enterprise-E's library.
Instead of being home to the interiors of the Enterprise NX-01 for Enterprise, Stage 9 housed only that series' cave set and various swing sets. Paramount Stages 18 and 8 housed all of the NX-01 interiors used in Enterprise.
Stage 9 became home for the Rura Penthe sets in the episode "Judgment", the bridge of the USS Defiant in the episodes "In a Mirror, Darkly" and "In a Mirror, Darkly, Part II", the Risan bistro, nightclub, and basement under the nightclub as well as Hoshi Sato's apartment in "Two Days and Two Nights", the surface of Archer's Comet in "Breaking the Ice", and the scenes on Rigel X for "These Are the Voyages...". The ceiling of the stage was actually seen in these scenes, as it was deemed a good fit for the interior of the complex.
Following the cancellation of Enterprise in 2005, Stage 9 was, for the first time in many years, put into use in non-Star Trek productions.
