Good point about diapers. My wife and I have been happy with the Kirkland brand diapers at Costco. If you do decide to splurge on diapers, you might consider the Pampers Sensitive diapers since these have a yellow line on the front of the diaper that changes color when the diaper is wet. It's a nice feature, but it's not a necessity. I agree that the wipes warmer is completely unnecessary. Here's another tip: before purchasing baby-related products, read the reviews on Amazon.com and BabiesRUs.com. It's helped us to only spend money on products that are really worthwhile.
