That stinks. [] In that case, I would definitely correspond with them via e-mail before I purchased the tank. They may be able to provide the other parts that you want (at a cost, of course) when you buy the tank....I really have no idea.

If not, like you said, you can always order the parts later and upgrade whenever you are ready. It might be a good idea to make sure that the tank is up to snuff before you buy a bunch of extra parts, anyway. I seem to recall that people who ordered from that company have had successful experiences, but the product itself my be faulty and you need a company who will work with you in case you need to make a return or exchange.
