Worth just checking with a hydrometer, but it sounds like it's finished. A dry wine should be around 0.990.
You can rack as many times as you like, as this does help clearing away the dross from the bottom, and sometimes the dead old yeast cells pong a bit!
I often rack twice anyway, as splashing the wine around helps to get rid of the old carbon dioxide, and of course, the smell, but remember that you're also introducing oxygen, so don't get too frenzied, or the wine may not want to last that long...
Of course, if you bottle it all now, you may get some sediment later on,and then all you need to do is decant each bottle!
I think I'd prefer to rack now, even use finings if you have some, shove a crushed Campden tablet in the new demijohn, and let it stand a day or so before you decide what to do from the above.
