When Selling used sets should you invest in original boxes?

I just got a great deal on 30+lbs of Lego blocks from yard sale. I plan on putting the sets together and buying the instructions from bricklink. After I have some fun putting them together I thought I would sell them on eBay. Many of the sets are retired and I should be able to get some money for them. What I want to know, is it worth buying the original boxes to complete the set. Also if I decide to keep the mini figs will it hurt the cost they go for. Thanks!
