depends what your trying to attempt exactly ele...
bump/normal mapping can't be achieved realtime by most cards, atleast not within DBpro ... there is a plugin which allows you to export the Normal of an object though.
Assigning Texture Vertex Colours (Baking) is alright for your Per-Pixel Lighting but again this is a different effect to normal mapping.
why don't you show us a jpg of the rendered model with all its bells and whistles ... also a copy of what maps you using (and what material settings) and can go from there rather than playing the guessing game
