Well, basically what I do is select all the vertices on half the model and delete them...then you can model just half the object and in the end duplicate the other side.
Or better yet after you delete half the vertices, select the other half, go to edit>duplicate box, then make an instance with the scale set to negative x (y or or z, whatever the plane you are duplicating across). This way now whenever you select a vertice on half the model it selects the same one on the other half and kills half the work.
As for selecting through, you can fix this by going to display>custom polygon display box, then turn objects affected to all, and back face culling on, hit apply and close. Now only the vertices and faces that are towards the camera will be visible and selected.
