Dead Rising 2 - 100% Playthrough, All Offline Unlockables (Part 1)

I wanted to get this out on Halloween and do a commentary for it, but i got a bad cold and my voice is just terrible right now.

Anyway, the idea here is to do a 100% playthrough, plus all the unlockable pieces of clothing and vehicle keys. For that i need to:

Use all melee weapons (unlocks the Hockey Mask)
Use all clothes (unlocks the Dealer's Outfit)
Kill a 1.000 zombies barehanded (unlocks Tattered Clothes)
4.400.000 dollars and both Bargaining Magazines (to buy the Knight Boots, Sports Car Key, SUV Key and Chopper Key)
Get Ending S (to unlock the Knight Armor)
Beat Jack in Poker (to unlock the Knight Helmet)
Get the Full Beard Moustache in Royal Flush Plaza (just a matter of finding it, it's not well hidden or anything though).
