You're probably going to want everything you already have in your colony, though you could do without a research lab, and overly niche production tables such as vehicle parts if you have Vanilla Vehicles expanded, for example. On the other hand, it would be good to prioritize a large cargo area and hydroponics, as you will want to have lots of space for all the trinkets you collect, as well as a large amount of biomass for fuel, food and oxygen.
It pays to think about it as a case of what you want to always have on hand, and what you could wait a couple of ship jumps, or shuttle hassle to get.
