You can use their familiar scented toys and sleeping pouch in the cage, but use a you-scented bonding bag.
I would suggest cutting small glider sized blankets (4x4") out of fleece, then sleep with those blankets tucked into your pillow case until you get your babies. You can add one or two blankets to their familiar pouch for sleeping in. It'll help with bonding.
After they've settled in, give them a couple days then put a fresh you-scented pouch in their cage and once they're using it, swap it out for washing.
And yes, the safest way to travel is with your gliders in thir bonding bag, inside a small travel cage or cat carrier. Buckled in, of course! You could also buckle the bonding bag in if you don't have a travel cage. But wearing it on you is the most dangerous of all, in case of an accident.
