Codes/I've searched

My check engine light came on last night. I pulled the codes:

P 0300
P 0303
P 0306

and the EGR
P 0400

Is this the infamous EGR fault code where I need to clean the port of the carbon buildup?

The car runs fine. I changed the coils, plugs, and wires last week. Why would misfire codes come up now? I asked a question that got no reply last time about the allen bolts that secure the ignition coils down on the exhaust side. If they are not tight at all could that affect the ignition coils from firing correctly? Will it harm the car to drive it short distances until I can look over it tomorrow?

Thanks for the info.
