I think that FME is capable of reading the Tiff World File associated with the Tiff. So if you use a Directory and File Pathnames Reader to read the folder that contains all your Tiff files. Connect this reader to a FeatureReader that reads all the GeoTiff files. These should all show up in your inspector in the right location.
If this is the case you could feed all the Tiff files to a RasterMosaiker. Or to a clipper and clip them with the desired polygon border.
I hope this gives you an impression on how to solve the problem.
