A couple of suggestions from my personal experiences:
Prices for flights can fluctuate daily. I have heard from some people that Tuesday/Wednesday is typically the best days to get the best prices on flights, but I'm not sure how true that is. Anyway, when searching for a flight, I use the Travel section on Bing because of its price predictor. It keeps track of the previous prices for flights, and makes a recommendation on whether you should buy now or wait for prices to drop based on previous behavior.
Look for shuttle services at the airport. For example, Super Shuttle will get you a round trip shuttle from the airport to your hotel in Dallas for around $18. Significantly cheaper than a cab usually is (even when splitting costs).
