Unfortunately I can't help you with the misfire.

However, your other 3 symptoms are exactly what I had when I first got my car. Wanna know what it was?

Clogged, nasty, grody catalytic converter. First, check to see that your catalytic converter isn't clogged or disintegrating. That could definitely cause idle bogging, trouble starting, and the catalyst efficiency code.

If it's fine, replace your o2 sensors. Then clear the computer with a scantool.

Don't drive with the CEL flashing, a flashing CEL pretty much means to stop driving immediately or else (very) bad things could happen. My thought is will the cat or o2 sensors... if you ran lean because of a bad o2 sensor reading, that could cause a misfire.
