If you are seriously asking what you need, then what you need is to take it to a shop. You don't have the tools to do this.
EDIT: You need at least 3 tools you probably don't have JUST to take the old BB out.
Bike shop will do the install I am ordering the parts else where. Sale ends tomorrow I think so I wanted to get the order in.
