Check that your squid supports it:
  squid -v

one of the options about disk should list ufs,aufs maybe diskd and null
as well.

If so, simply change the config file and reload. There is no disk actions
needed to change between ufs/aufs/diskd.

No. Having two acl on line line only blocks when BOTH match the same
request.

I could not see anything wrong with them.

If you like to try another way of writing the same thing would be:

  acl workHours time MTWHF <hours before lunch>
  acl workHours time MTWHF <hours after lunch>

Yes, with some restrictions. Only the part of torrent that goes through
HTTP can be blocked by Squid.

Torrent:
 acl torrentSeeds urlpath_regex \.torrent(\?.*)?$

Rapidshare:
  acl dlSites dstdomain .rapidshare.com .rapidsharemegaupload.com
.filespump.com

I'm not too sure about the rapidshare domains, there are likely some I
don't know about, and some of those may only be look-alike sites.

You should be able to easily upgrade between 3.0 releases. The main
meaning of that "STABLE" word is that we wont add configuration changes to
3.0 any longer, and features require a very good reason even to be
considered.

Squid needs to be started as some high-powered user. Commonly root, but
the requirement is only for admin access to certain networking operations.
This is needed by the master instance to catch system signals etc.

The configuration should then specify some very low-level user account
used to do the more dangerous stuff such as listening for public HTTP
requests. That only needs read/write access to logs and squid data dirs
IIRC.
The default is usually set and prepared properly by the distro packager.
