I'd like to change various log files (particularly auth.log) to retain info for anywhere from the last 30-90 days. Right now it only has about 4 days worth of info. How do I modify these settings via the GUI or command prompt?

Thanks!

Ubuntu uses logrotate

You configure it in /etc/logrotate.d

Sample syntax:

   /var/log/messages {
       rotate 5
       weekly
       postrotate
           /usr/bin/killall -HUP syslogd
       endscript
   }

for full configuration options see:
