First of all go double gather prof. Then accumulate full stacks of ore, herb, linen, and leather. Go to the AH, and sell at the price that most people are selling for (these prices are usually the market standard and will generally sell). Be patient, some items won't sell right away, however the cost to put up the auctions are pittance compared to the price you'll make off of it, so put it back up for auction.
While the world event is going on, take full advantage by selling the exact items that are needed for the war effort, they're guaranteed sales (as long as they're still needed for the war effort). Don't think of yourself as greedy, those goods are going to get to the war effort soon enough. It should be perfectly acceptible to sell these items in the AH for a nice profit, especially if you don't have any desire for the rep or the crappy green item.
