Duct tape first then felt lagging. Not really necessary but I like to do it as it's an extra barrier.
Shortest run is the best and then split pipes to each end of new rad valve positions. Give finished pipes a good clean to get rid of all the flux residue and stop the green.
Edit: duct tape laterally along pipe and then just fold it round. Don't wind it.
