All of the above plus you may want to add the CA-2A T type Leveling Amplifier. 

Agreed on volume automation.
You can do this on either the track... or per-clip basis.
I like to do this kind of procedure on a per-clip basis.
You can even out the volume between sections using per-clip volume automation (which can often be quick/static/fixed changes in gain)... then you've got separate Track volume automation when you go to mix.
 
I'd avoid normalization as that'll simply raise the volume of the entire track... to where the loudest peak is at full code (0dB).  It's no different than (non-destructively) turning up the track-fader until the loudest peak is at 0dB.

Volume automation and a little compression to even things out.

+1 to Bristol Jonesey's and John's comment.
 
Use Clip gain to level the playing field, then compress.  The CA-2A is lovely on vocals.
 
I often put the PC76 before the CA-2A to catch any peaks left after the clip gain.
