Quest List - I haz a Question

[Hessah]

OK maybe more than just 1 question..

I've been updating all the broken formats in Quest List... like changing all the Bless Lix (2) to Blessed Lix (2) etc... so that they're all redirecting properly...

Question 1:
Is there a way for me to view the list of existing pages in wiki? I'm worried that I'm creating new redirections that already existed.

Question 2:
Do I have to create a new redirect page for every "HP Potion (Tier 1)", "HP Potion (Tier 2)", "HP Potion (Tier 3)" etc?

Question 3:
There was a "Lucky Lix(1)" page, but i've changed it all to "Lucky Lix (1)" -with a space- is it possible to delete the old one to stop confusion? Is that something only you admins can do? Or just leave it?

Question 4:
Can I, or someone else, change the name of Weapon Title Merchant Bran? It's currently "Weapen Title Merchant Bran".
