The wall boxes contain isloators, so whether the new leads have inline isolators or not does not matter.
The push connectors are designed to push over the existing threads on the wall box outlets. Disconnect the cable that goes to the splitter from the TV box & this should connect to the wall box. What you must not do is use your own coax, as the coax used for aerials & satellite dishes is not up to Virgins specs.
You can use WiFi for the TV box if the speed of the connection you get is high enough.
