Where can I find cheap flight tickets from Detroit to Miami in Feb/March?
I'm looking for around $200 or less... what are some good sites/travel agents/deals? Are certain days of the week cheaper for flying? Would it be cheaper to fly from Chicago to Miami?

check out www.spiritair.com I believe Spirit Airlines flies into Lauderdale, and not Miami, but depending on what your plans are (for example, if you're staying near the beaches) Lauderdale is as convenient as Miami International. I've signed up for Spirit's email specials, so every Tuesday (and sometimes more often) I get notice of their upcoming sales. I also belong to their $9.00 flight club, which can give you additional savings. All this can be done online. You need to be aware with Spirit that it's a no-frills airline. You get nothing on the flight without charge - beverages, snacks. No pillows, blankets anymore. And they charge you for each piece of checked luggage, although I pay for that online beforehand where it is considerably cheaper. I don't believe it would be cheaper to fly from Chicago...it's the same distance, maybe even a bit further as Chicago is even further west. And then you have to get to and from Chicago to begin with which is going to add cost.
