Agave nectar is not primal. And I think dates are discouraged since they contain so much sugar.
I've found that with paleo/primal, there isn't really a huge use for cupboards. Most everything you buy will need to be refrigerated or frozen (meat, some veggies), or just left out in a bowl or basket (fruit, some other veggies). Just about anything that comes in a can, box or bottle is non-primal. Except for spices - those are certainly good to have. I think in my cupboards is a jar or coconut oil, a bottle of olive oil, a few tins of tuna and a bag of sunflower seeds. Oh, and various boxes of tea.
I had slowly switched to a primal way of eating, so I just ate the rice, pasta, oatmeal, etc. that I had and didn't buy more. I came from eating a vegan diet and passed through an transition stage where I started adding more meat and eating less grains. Oh, and some I gave to my parents - they would have just bought it anyway.
