Some logs, rocks, feeding bowl, and a hide would be good for your dragon. not too sure on the bed and blanket, I know lots of people use them but there not as necessary as the others you mention.
It's also advised to keep the vivarium fairly basic when they are young to help make finding crickets and other live food easier, and then to slowly add more decorations as they grow.
Good luck and can't wait to see some pictures once you've got him/her.
Edit: once you get your lights and other equipment id get it set up as soon as possible, it took me quite a while to get the right temps and then I realised I had really high humidity on a night once the lights went out and had to make adjustments to the vivarium.
