Unpack your kitchen stuff onto a table - dining table even in a different room is perfect and preferable to filling the kitchen, with nowhere to put anything and not getting organised. Then you can see what you've got and work out where best to put it all for the layout.
Planning is key. Make sure you have a think about where each item of furniture will go. This will save time wasting with moving items around. I found it helpful to have a couple of people unloading the van and then a couple unpacking.
