No. (This is one of my favorite feature requests)

Yes. 

1) Save the current state of the layout in pcb. 

2) call gsch2pcb with the changed schematic

3) If you changed connections, an updated netlist will be produced. If 
you changed the value of components, they will be updated in the pcb 
file. If you removed some components, they will be deleted in the pcb 
file. If you added some components, a file $NAME_new.pcb will be 
produced. This file contains all the footprints of the added components.

4) In pcb do 

   a) File - Revert    (if the changes affected the layout)

   b) File - Load_layout_data_to_paste_buffer (to put the new footprints 
       somewhere on the layout with the buffer-tool)

   c) File - Load_netlist_file (if connections were changed)

The tool xgsch2pcb reduces these steps to a single mouse click.
