Unfortunately, there is no way to tell how long your item took before it sold itself on the Auction House, or how much interest was generated in your item (reason being that the interest generation would be hard to prove because the AH displays all the items in a whole page).
However, there's the Date available for you to gauge which day it sold and how much did you gain (after the transaction fee) in gold in that particular transaction.
Order IDs would actually be used in case an item did not process correctly and the buyer/seller ended up not getting the item/gold respectively.
Also, if you want to gauge on the pricing, why not see what others are putting their items up for in the Auction House respectively?
However, your approach (1 to 2 minutes on deciding pricing, etc) on the Auction House would be insufficient for you to gauge how much you would want to price your item at.
If you really want to milk every cent out of the item's value, you need to start researching and pricing your items competitively. This is how it also works in the real world, companies price their items based on competitors and value-added services via research itself.
Or you could just price it randomly, and see if any sucker buys it at that price (sometimes people are desperate for an item. :P).
