"The Daleks(yes, they died, but as part of the wiki) would not be the only additional escapees; they would be joined by the Skaro Degradations, the Horde of Travesties, the Nightmare Child, and the Could've Been King with his Army of Meanwhiles and Neverweres,"
Or those items and beings allready had been destroyed during the war. Remember that at the point in time where Galifrey fell, the war had been going on for a long time, sometimes even on repeat.
Galifrey was shown to be under attack from pretty much all the dalek, they probably even brought in the last few, and nothing else.
Even if they were present at the time when they removed Galifrey from the timestream, they would still be dead. There was a insane explosion when it was removed, probably the Moment setting off a localised catastrophic event, and you even see wreckage from the Dalek fleet fly past the camera.
For all timeline purposes, it happened exactly like it's allways been described as happening. Galifrey exploded, Daleks, sans 3 survivors, exploded, the Doctor thinks he did it.
Except the Moment never destroyed Galifrey as it has always been thought, the Moment brought 3 Doctors together and used their combined experience and guilt to formulate a solution.
It's the ultimate instance of a thing you have gone ages regretting and then suddently you come up with the solution on how to prevent it many, many years later. Nothing you can do about it, the Doctor can, well, the Moment could make sure the Doctor could.
As to the reason he doesn't remember it happening that way, probably the Moment again, punishing the Doctor for even being willing to use such a power and do such a terribly thing. Also, it needed the Doctor to work on a solution since being all powerful doesn't necessarily come with a great imagination.
Appearently 400 years was his penance and now the Moment has absolved him from it. How Trensalor happens, who knows. The Doctor that was headed there was a man wracked by guilt and selfinflicted torment. He might still end up there somehow and still come out on top, wouldn't be the first time he's escaped from certain death before.
As for Galifrey coming back? It allows for some new stories and it also gives the next reincation a clean slate to deal with all the things that now survived on Galifrey (Rassilon and his band of whackjobs comes to mind) and the fallout from that. It also means that there will be a natural opposing power to the Daleks (the amount of Daleks seen in the Asylum episode could probably wipe out all life in the universe three or four times over). What will be interesting is how the Doctor will manage to keep them from going at each others throats again.
