-mixlfe is not recommended by Dolby because can produce artifacs, but you can make the two versions and compare.
-phaseshift is not recommended if source is ac3 because the surround channels are already phaseshifted, if you do other phaseshift the result was wrong.
-normalize is the parameter recommended after a downmix to obtain the max volume, instead the arbitrary +6dB

I gather DRC is a good thing since it lessens the difference between loud things such as bangs and normal speaking, so when increasing the volume so I can hear them speaking (I'm slightly deaf) it won't blow the family away when a bang occurs... is that right ? and if so, can we do DRC with eac3to ?

DRC is a good thing
when play the audio, but use it to reencode is lose quality. If you play with PC you can use AC3Filter to add DRC on the fly. If you use receivers there are a 'night' mode to play.
Now eac3to don't decode with DRC activated and Aften can't do correct DRC management.
