A couple protips for those that seek advanced guidance:
PoBs use the same logic as your ship's inventory, so ammo does not take up cargo space unless it does on your ship. You can have potentially an infinite amount of munitions aboard due to this.
Store your FWO in multiples of 240 to more easily measure how much food you have.
Crew are always last in the base shop.
If your base is not in a combat-heavy environment, it can last for days before it wears and tears itself to death. However, if some lolindie comes along, hope you have nothing valuable aboard that would be particularly missed.
Bases are either factories or supply dumps. Determine what yours will be before you build lest you run out of space.
Continuing on with that, if you feel ballsy and/or are too cheap to advance to Core 2, make an annex base right next to it. Just drop a reasonably large transport/train and only use it to haul from Base A to Base B.
How to get away with metagaming: PoB Edition

How I made my first billion
(If anyone asks, you can claim you got the goods from a third party. You're the first party, the people you're selling to are the second, and the PoB is the third.)
You have your PoB.
Make an (to the untrained eye) unaffiliated character.
Get a Freelancer ID and a large transport of your choice. (I go for either a Pirate Train or Serenity)
NPC Pirate in that puppy and grab valuable cargo.
Vamoose back to your fortress of deceit and evil and log a legit trader to haul your ill-gotten booty for high profits.
Rinse and repeat, with no-one (lawful, that is; Admins know all, and, well, I haven't been slapped for it yet.) the wiser.
Ironically, this has profits comparable to powertrading if you interdict the right shipments, without any silent trading or anything, and on an off day, you supply the base with materials to make goodies such as modules.
Disclaimer: This trick is kind of a grey area, and if a green tells me to knock it off, I'll knock it off, and baleet this bit so I'm not a bad influence.
