Challenging Riddle...Please help!

Hey everyone! I can't figure this riddle out and was wondering if I could get some help! It's Harry Potter related, but I think it can be solved if you don't know anything about Harry Potter either! All I know is that the answer is 2 words! I would really appreciate if someone could help me out!

Ar ya ready for this special quest?
At end there is an old treasure chest!
Not full of fool's gold,
Shiny, hard, and cold;
But a book, mateys, and them's by far the best!

To solve the riddle, put your THINK CAPS on.
The name of God may help you if called upon.
Each clue gives another,
Another, an other;
And all of them leave you confused as Ron.

Ar, now you're coming along quite well,
It'll all be over after this short spell.
A "paper" or "stand"
Will help hold your hand,
And bring you closer to being quite swell.

So follow yer instructions to the T.
Ar, no one knows more words than he.
In the music we wrote,
We marked a grace note,
Now yer job: tell me who the winner B.
