I am just about to lay down a layout of Peco Setrack Insulfrog Code 100.

I have some confusion with regard to the wiring, do I need to feed at each toe and isolate the two lines coming from that and then feed those two lines after the isolation break.

Or if I read the Peco catalogue correctly, the Insulfrog does this all for me and I only need to feed the track at regular intervals.

Some guidance would be very much appreciated

The point directs the frog power to the route that it is switched to, so if it is set to the left hand route only the right hand rail of the right hand route will have power on it. So you may decide that you need additional feeds. If you do then its advisible to put isolated joiners immediately after the point to prevent the possibility of shorts which will trip your DCC supply if a wheel touches the blade of the route which is not set ie if taking the right hand route a wheel on the right hand rail may touch the point blade for the left hand route. This possibility is I suspect more likely with Setrack points than Streamline of any code as they are pretty crude in their frog and check rail distances resulting in modern fine wheels stock often lurching through them

Hi Diggy
You don't need to do anything to Insulated frog points other than add additional track feeds to sidings or loops etc so as any locos stabled in a siding can still be moved, have their lights turned on, sounds operated etc. In other words every rail of the layout should be DCC live regardless of the points blade position.
By adding additional feeds you wont get short circuits at the point blades, as the open blade is at the same polarity as the stock rails it adjacent too (This is the opposite when Live frog points are used and insulators are then very much needed).
However, and very occasionally, you may experience a short circuit as a metal wheel passes over the insulated frog and the wheel is able to touch momentarily both rails immediately before or after the frog, as these two rails will be at opposing polarities. Then its wise to install insulated joiners immediately after the frog on the ends of both Vee rails.

This is all covered on my web site here Points
and DCC items here DCC advice
