What can or should I do or use to get more heat out of mire fireplace?

My fireplace is a wood burning fireplace. It's 2-2.5 ft deep and 3 to 3.5 ft wide. I've got a standard grate in to hold the wood for burning. I'd like to get more heat out of it. Seems it's only about 10% effective at best. I've looked at Fireplace Heaters (grates with blowers) and that might work. Cozy Grate seems to look like it might be the best. I've also thought about adding Iron plate around all 3 sides of the fireplace to help generate more heat. Think this would help? Anyway I'm currious if anyone knows what more I can do to get more heat outta this sucker. I'm payin bout 60$ a rick (cord) for wood and would like to garner as much a financial benefit from it as I can. Oh...and another thing..Can I add a wood burning stove to a standard chimney without any real modifications? As you might tell I'm a city boy...HELP ME?? Thoughts?? Brrrr...Cold here in Indiana.
