MustangFilter: 2006 v6 Ford Mustang giving cylinder misfire codes. Crank sensor and pulley recently replaced, the shop tells me to replace the coil pack. Looking for other root causes before I take the plunge?

About two weeks ago, my Mustang started to stall out in idle, so I took it to my shop. They replaced the crank sensor and pulley, and all was well. For about an hour. The check engine light came back on, I experienced a pretty severe drop in power, and the check engine light began to flash (indicating a misfire). Having the error codes read showed 0302 (misfire in cyl. 2), 0306 (misfire in cyl. 6), and 0300 (random misfire).
The garage initially told me to replace the coil pack and all would be well. Since I don't have a ton of money to my name, I'd rather be sure that the coil pack is the cause before I turn to them again. (I prefer to do small maintenance myself, so that's part of the hesitation.) I've done the research on these codes, but seem to get conflicting opinions about what could cause the misfire, and specifically why ONLY those two cylinders are experiencing it. Any thoughts, mechanics of the Green?
