After doing some more testing, I found that FLAC > Vorbis preserves ReplayGain tags while conversion to mp[34] does not. Sounds like a GStreamer issue. Not really sure.
As far as ReplayGain playback is concerned, the plugin does not work correctly. It lowers the volume but none of the settings have any effect.

At this point, the Rhythmbox core doesn't actually store or use any
ReplayGain information directly.
The way ReplayGain currently works is that an rgvolume¹ GStreamer
element is added to decoding/playback pipeline; this takes the
ReplayGain info directly off the GStreamer bus where it was put by the
demuxer or decoder element.
The only reason to store ReplayGain in the Rhythmbox database might be
to satisfy user's curiosity - it could be displayed in a column or
shown in the track properties, I guess. Not really sure if that's worth
it :)
