The visitor suit

So after reading all the threads about the visitor suit that you get to upgrade, I was wondering can anyone please give me an organized list on how to upgrade it and not screw it up. This could be great for me seeing as I dont have alot of money for equips, and I dont want to screw it up! Bascily I am looking for a list that tells me: How to upgrade, How to get the medal things, how to get the scrolls to upgrade(like are they normal scrolls or speacail ones?), how to make i permanent. Thanks to anyone that can help me!

P.S. You will also get a free virtual cookie!
