I am wondering if it is paranoia and/or privacy overkill to block out one's computer name when posting terminal output in public forums? I don't know enough about networking to know if it's possible that this information could make one's system vulnerable somehow (though I suspect not?) and was hoping someone could shed some light.

It depends on your privacy concerns...
Your username and hostname could be used by someone who cracked your wifi as a "hint" to access your samba/netatalk shares. It can reveal some info about you depending on how you named the host and your username...
But these are not a system vulnerability, but a privacy concern. I, personally, change my hostname and use non-identifier username... just in case.
