Inventory, new equips types, equip bonus

Hi guys!
I'm playing this korean version: http://burgerburger.kr
You can play with google translater.

So, there you will find inventory system, skills, new equipments slots (necklace, ring and boots), equipment bonus (like x% drain hp, +5% damage, +2 Defense...), a coin system (they use burgers to buy stuff. There is a public market where players sell items for burgers), quests, lots lots and lots of npc, mobs, items, equips, quests, areas, maps, everything.

So,maybe you guys can do any of this? And please, a system that shows player level on character, like this:
 Lv. 10 - MrMota
      (  º _ º  )
      //l       l\\
        l       l
       //       \\
