How do you get a trade to go from in progress to completed

Once both sides mark the trade as complete it will automatically be moved to the completed trades tab. You can mark it as complete by opening the trade and selecting "transaction complete" from the drop-down menu at the bottom of the page, and your trade partner should do the same once you both have received your cards. 

No, you need to go through the steps of package/payment sent, package/payment received, then completed. Be sure to update between the steps.
