New vanda coming help set up

[Mercurianmad]

Hi guys! I’ve got a new “black” vanda coming and I need to know how to set up the basket for it. It’s going to be hanging in my sunny windowsill next to the humidifier with the oncidium. I’m thinking of hanging the basket from the window lever, where my hand is in the picture. Pictures below. Thoughts? Currently it’s a 4 inch plastic basket. I am able to purchase a 6 inch and an 8 inch vanda basket additionally. Do I repot it when I get it? Can I just put the orchid in the basket? Does it need any potting medium? Or do I just set the vanda in the basket. Lol. Help! Thanks.
