Converting from a TIFF project to JPG is pretty easy. Just batch convert all the tiffs to jpg (only change the file extension), open the hugin .pto file with your favourite text editor and replace all ".tiff" occurences with ".jpg". No need to recompute any keypoints or realign the images.
An alpha channel just defines how visible the pixel should be, from complely opaque (visible) to completely invisible. If you put a background layer behind the actual image layer (using GIMP or Photoshop for example), you should be able to "see through" the image layer where the alpha layer is not completely opaque. Note that both GIMP and Photoshop also have to option to add a mask to a layer; this is different from the alpha channel (for instance, flood filling a layer with a mask will overwrite the alpha channel, but not the mask) but can be used for similar purposes. Enblend uses the alpha channel however, since tiff files do support alpha channels but not a separate mask. If you understand the concept of an alpha layer, as described above, you should be able to check out the alpha channel without too much trouble. If you make the background layer contrasting to the image (for instance, completely red or purple) it's quite easy to see what the alpha channel does. Does this help you?
