drawing a line (splitting a surface)

Hi there,

I am a newbie to Blender software world. I got an aircraft model in *.3ds extension. I imported the model into blender work environment in wireframe and edit model. The first problem is I need to split a surface into two parts. The other problem is the surface is grouped into a name (stabilator) (seen when ouliner is used) once after splitting (drawing a line in the middle of the surface) i want to rename stabilator into two (stabilator1 and stabilator2).

Sorry if I am not clear with my question.

Please let me know the procedure.

Grately appreciate your help.
