You don't tribute anything, it is a Synchro Monster. You have to send a Tuner and one or more DARK non-Tuner monsters from your side of the field to the graveyard. As per the usual Synchro rules, their combined level totals must equal Dark End Dragon's level, which is 8.
Because Dark End Dragon does not 'destroy' anything, Stardust Dragon is unable to negate it.
Dark End Dragon has 2600 ATK.
Dark End Dragon has 2100 DEF.
Dark End Dragon is not in a set as such, it is a Shonen Jump Prizecard, awarded at Shonen Jump Championship events.
Slifer, and the other Egyptain God cards, require three monsters for a Tribute Summon. (They can be Special Summoned as well, but are sent to the Graveyard at the end of the turn.)

A Nenufar Dragon is one possible result of breeding a Plant Dragon and Water Dragon. A Dark Dragon is one of the eight basic elemental dragons. If you breed these two dragons you may end up with any one of a variety of hybrids including a Pirate, Butterfly, Burning, or Petroleum Dragon.
Bottomless Trap Hole destroys the summoned monster as well as removing it, meaning that Stardust Dragon can tribute itself to chain its negating Quick Effect to BTH's activation. This negation effect will resolve, negating and destroying Bottomless Trap Hole. Then in the end phase, Stardust Dragon will summon itself to the field.
As long as that Stardust Dragon had been special summoned properly by Synchro Summon (ie, it did not reach the field via Starlight Road), then the opponent is free to Monster Reborn it before it tries to special summon itself in the end phase.
