Twiglet, much depends on your ability and that of your party. The climb down at the top end of Edward's (just as you turn left out of Gnome) is about 4m and very slippery, but is easily slithered down by experienced cavers or those who have simply learned to control a descent by bracing their legs. I have frequently taken novices here and always rig a rope for them, but at the same time use it as a test to see if they can grasp the 'bracing' concept - useful for all sorts of things in caving.
The 'crux move' of the route you describe is the traverse about halfway along Edward's Shortcut. This is exposed but a very easy traverse for those who are confident about having their feet on one side of the passage and hands on the other, but nonetheless many otherwise capable cavers dislike it. Rigging a rope for the less experienced is recommended but there isn't much to tie it to. You'll have to improvise.
There is nothing else to trouble you on this little circuit, but President's Leap requires care; this is an exposed ledge just before you arrive at the Crossroads (when coming from Selenite). This is so named because the SWCC President fell down it on a solo trip some years ago and had to be helped by a party who came along subsequently.
If there is anything else you need to know just ask - enjoy your trip.
