Try something like this:
cp /etc/apt/sources.list /etc/apt/sources.list.`date +%Y%m%d%H%M%S`.bak
sed -i s/us.archive.ubuntu.com/mirror.cs.umn.edu/ /etc/apt/sources.list

The UMN mirror is never slower for me and it's MUCH faster around
release time. I'm a bit paranoid, so I actually specify both
mirror.cs.umn.edu and us.archive.ubuntu.com. Apt prefers by version
first then by the order of mirrors in the sources list. So by putting
both, I end up getting downloads from the UMN mirror while ensuring that
if something were to go wrong there, I'd always get the latest packages
from the official URL. The downside of listing both is that you have to
download the package lists from both places. Given that I've never had
problems with the UMN mirror and it's been at least a year, it's
probably time that I can start trusting it.

Yes. Loopback-mount the .iso and add it to /etc/apt/sources.list using
apt-cdrom. I've never tested this. The following link might be helpful:
