Once you're done modeling the character and you want it to be one piece of geo... the way I like to do it is merge verts. Go to the front view and choose faces. Select the faces on one half of the model and delete them. Then duplicate it under "parent". Make sure your tolerance in the merge verts option box is very low (about.001), choose all the ones down the middle in the front view and deselect the ones around the lips or other areas where they may be really close together. Hit merge and then go back in and do the lip area and any other are you deselected earlier manually.
