Voice-over: conventions of the genre

Hello,

I have recently taken a role of a sound engineer in a voice-over recording studio. Quite a big number of demo recordings has been done already, so now I'll have to process them, if necessary.
From what I've read in other posts, I presume the following techniques might help:

1) If the dynamic range is too high (for reasons other than creative - an artist often moves away from the mic), apply subtle compression - never more than 6 dB.

2)Normalize.

3)When applicable, enhance and over-compress (stereotypical commercial sounding)

4)If the proximity effect had not been creatively used, try to get rid of it with EQ's (no bassy sounding).

5)Get rid of over-emphasized 'S' and pops.

6)EQ tonal imperfections caused by mic placement/room.

Is there anything else I should do? Is there something I certainly shouldn't do?

Thank you!
Anton
