To remove squid, and all configuration files:

sudo apt-get purge squid

To then install squid

sudo apt-get install squid

When editing system configuration files, I highly suggest you first back up the original.

sudo cp /etc/squid/squid.conf /etc/squid/suid.conf.orig

When editing files, do not delete anything, use comments

#Original line(s)
#Date / reason for edit(s)
New line(s) with edit(s)

Your question about the squid conf file should be separate. As a hint, google search regular expressions.
