It's definitely worth doing yourself. The satisfaction of changing your own brakes is... satisfying. It sounds like you're a heavy braker so you might want to upgrade to a more performance grade rotor and pad set like Power Stop Evolution or similar that can take the abuse. I can get away with cheaper sets because I'm not a heavy braker.
I had never changed brakes before a year ago and now I've done a set of both front and rear. It's not difficult at all... EXCEPT corrosion and seized bolts, etc. That's what takes the most time, especially if you live in a salty state. Just take your time, be prepared to fight bolts, and as Ticker advised, seating the pads correctly after installation is very, VERY important. Follow the break-in procedure provided by the manufacturer to the letter and you'll be fine.
