I am looking for a method to use audio equalization on my Linux PC to compensate for hearing loss. Pulseaudio-equalizer seems to have the amplification variability and frequency bands needed. My concern is that I need different equalization on the right and left channels; my hearing loss is not symmetric (I am using headphones). Does Pulseaudio-equalizer have this capability (I cannot find it)? Or, is there other software or methods that may achieve what I need?

Your fears are founded : rear and front output are the same only when the source is simple stereo (i.e. music, or basic divx films). For other sources (DVDs, but most importantly games), they are different, and you will have a bad experience...
I Have the same kind of setup as you, but with two sets of speakers and a headset. The only solution I've used so far is use only the front output, with an audio "strip". That is crude, but works...
I'm looking for alternatives, but haven't found yet...
I have made best experiences by setting up a network distributed audio solution based on both Icecast2, and uShare (for uPnP/DLNA streaming).
Any receiver connected to your LAN (either by cable or by WiFi) will then be able to acess audio from your server in the following way:
Stream a playlist: Combine icecast2
with ices2
or Ices (for mp3)
Broadcast the sound of your local soundcard: Combine Icecast2 with darkice
Make your library accessible: Run ushare
When Icecast2 is broadcasting audio any device capable of receiving Internet radio streams in Shoutcast format will be able to tune in. This can be an old PC, a mobile phone, or a special Internet Radio device, just to name some examples. The devices do not need to be compatible to each other.
A short tutorial on how to set up Icecast2 can be found here. Some notes on ushare are found in this answer.
Icecast is able to stream more than one stream at a time. Therefore you will be able to select different broadcasts on different locations.
The above solutions still are available. A newer approach can stream the local sound to a Chromecast or DLNA device: How do I set up live audio streams to a DLNA compliant device?
Instead of uShare we can also run minidlna for UPnP-sharing of media.

Looks like this was implemented in PulseEffects as of version 4.4.2. See this GitHub issue for more details.
To install PulseEffects refer to the README for instructions for your OS. Ubuntu specific instructions can be found in their wiki.
