Ghusal and wudhu, glue to stick quraans

As salaam mu alikum Mufti Saab.

I have two questions:

1) When taking a Ghusal does one have to make Whudoo again to perform Salaah
Since Whudoo is already made at the beginning of Ghusal.

2) Is there a special Glue that one has to use to stick pages on Quraan and KItabs.

Appreciate your response
