I currently have 5 Imperial levels not counting ones the games give you. Yet, I only have one active assignment at a time and the other two just say "waiting…" So do I just not have enough levels yet?
Edit: My gf plays on Android and she always has all three assignments active. Maybe it's an iOS issue.
I think you have a bug that will require a reinstall! Sorry!!!!!!! You can try restoring from a backup, but to my knowledge, the success rate there has been low. You can try contacting Disney customer support for help, as they provide the support for the game.
In short, stock piling helps with the imperial quests going forward. When you complete a quest, the next one may ask for an item that you have already stocked. So, in general, you will likely get paid back for those items you paid credits to generate. That said, you will do better in the long run building floors that generate credits as a means to make credits. And, if you are diverting too many credits to your inventory you will make less money over time.
In answer to the other portion of your question, many of the lesser items will re-appear in later quests, just in large quantities.

I believe we just have to wait because they are creating new ones for us. Lord Vader has a message that reads "It would be unfortunate if you lacked patience while we gather new assignments."
