The no use of mobiles whilst walking on the tarmac is not purely related to refuelling risks. One of the reasons is that people tend to unconsciously walk about whilst talking on their mobile phone.
There have been multiple incidents of people walking into spinning propellers while distracted by their phone. Hence the request to leave them off until you reach the terminal.
As for seatbelts on or off in an airplane being refuelled, I can't recall any fires occurring during refuelling with passengers inside, but I can recall accidents where a taxiing aircraft has hit a plane at a gate, so I would say you're safer with seatbelt on.
