You could also consider using Silicon Prairie's Paragraph/Character Tools. These will let you map Word's override styles and differently named styles to use specific ones from a template. See: Silicon Prairie - FrameMaker Products
Quite quick and painless. Not expensive either...
There's also Cudpsan's HuntOverrides utility that creates a hypertext list of paragraph overrides that can be used to work through a document. See: Cud Project: CudSpan Plug-ins Page (look under the FM10 plugins).
