Character alpha with Shadow in Cycles

Guys, im having a problem in render pass. In this scene i want to separate the floor and the character, but i want the shadow keeps with the character, not with the floor, i need both shadow and the reflex with the character. Anyone can help?? Thx a lot!

The shadow and reflection ON the floor can only be in the same render layer as the floor. However, you can seperate everything in render passes.
