Tissa,
If I understand you correctly, you did the B+W conversion by changing the colour mode to greyscale. If you then merge the two copies of the image, one of them is converted to the target colour mode.
Keep in RGB mode and copy the photo into a new layer (same document).
Do the BW conversion for one layer either with Channel mixer or Hue/Saturation or any other preferred method. I prefer channel mixer because it gives great flexibility.
Then erase or mask the pieces you don't want to see. If you make a mask, you can always revert to your original image, so mistakes are more easily corrected.
Even more simple: In your original photo, select the areas that you want to be B+W. Feather the selection 1 or 2 pixels for a clean edge.
With the selection active, create a Channel mixer adjustment layer and do the B+W conversion.
You can always correct mistakes or adjust the selection by painting with black or white in the layer mask.
Hope this helps
