ideally, alignment should be done all together....

load the MWmap_c tga into Photshop at its correct size........then load map_t and map_h into PS... but upsize them to be the same scale as map_c...then move them on top of map_c as new layers

adjust them as layers...moving and changing their opacity as necessary...as each is aligned then lock them together....when all done......make only the layer C as visible then save it...then do the same with map H and map T...save them as new tga's greyscale no compression
after that reload the T and H tga's and resize down to a quarter of C

all should then align correctly....... but your sea bumps may not be misalignment...... but just need the edges of their skirts pulling down at the water/land interface...using the blur tool in FMB
