I'm curious as to how the spacecraft is being neutralized. It seems to me like propulsion via electrons would just build up a huge charge on the spacecraft, requiring higher energy photons to eject new electrons and maybe causing arcing.

It's not possible exactly for this reason to be a continuous source of propulsion, but could operate for short periods of time and provide the fine propulsion. This is something that's being developed with projects due to start this year.
