You'll need to defeat the Elite Four again and they'll roam by their selves without manually going back to Route 7.
I'm pretty sure they go away permanently if you kill ANY type of legendary pokemon. well when i killed tornadus a few days later it came back
Landorus is found at the back of the abundant shrine, however, it will not appear unless both tornadus and thunderus are in your party.
Provided Tornadus faints during a battle and you've saved after fainting it, it will respawn once you beat the Pokémon Champion. N will act as the Pokémon League Champion during the first challenge of the Elite 4 until you beat them, him and Ghetsis as well as capture Reshiram.
you dont
No. Just like in Pokemon Pearl with the Pal Park you can only trade from Pokemon pearl to black, not back

if u have Pokemon black, u get a tornadus.if u have white u get thundarus. if one of ur freinds have pkmn black or white, ask them to temporarily trade u a tornadus(black) or a thunderus(white) so u have both. now, put them both in your party, then head of to the aubondent shrine(sorry for spelling) search there and u will encouter a landerus.( i highly recomend u have at least a lv.70 or higher. if u have any questions just tell me and i will hapily answer it. happy catching! p.s, when u have caught landerus trade tornadus or thunderus back to ur friend. don't worry,as long as u have caught landerus, it wont go away if u trade tornadus or thunderus.
If you killed Tornadus, you can either restart (it is always good to save before a legendary battle), or you can wait for it to respawn. In the case of Tornadus, it might just take going back to a town and then using soar again. Other people have reported that working. If it doesn't though, you can try beating the elite four again. That usually brings the hard legendaries back, if you killed them.
If you killed Virizion, don't save! Turn off the DS and go back. If you save, he will not come back.

No, you do not. Since you can't trade back.

You cannot. Once in Black/White it cannot be sent back
A lot of people back in that time was racist.
If you did,just go to the pokemon league then beat the elite four and the champion
