We are comparing an Apple to a Pear, LAMP is not the same as LAMR or a
Ruby on Rails install. Please stop comparing it, you are doing
nothing useful by doing that.
What is mongrel? Let's see here if this quote satisfy's you.
"Mongrel is a small library that provides a very fast HTTP 1.1 server
for Ruby web applications. It is not particular to any framework, and
is intended to be just enough to get a web application running behind
a more complete and robust web server.
What makes Mongrel so fast is the careful use of an Ragel extension to
provide fast, accurate HTTP 1.1 protocol parsing. This makes the
server scream without too many portability issues.
See mongrel.rubyforge.org for more information. "
A bit technical, but Mongrel is a Web Server. Like Apache, or nginx
or lighttpd. Except that all it cares about and knows about is the
application in which it is running. Technically you can run it on
port 80 (if you run it as root) and remove the whole extra web server
from the equation. Mongrel is for Ruby what mod_php is for Rails (bad
analogy). It does all the dirty work and forwards the end product to
Apache and then to the end-user. You can compare it to Tomcat or
Jetty I guess, however that's not here nor there.

Frédéric has pretty much gone into the other problems you addressed.
However, the best method of updating/upgrading typo depends on the
Let's say you use SQLite3
1) backup your databases in db/ to a separate location
2) unarchive the new version of typo in a separate directory (for
staging or testing purposes).
3) copy the backed up databases (do not move them, we want to keep a
pristine copy still somewhere) to db/
4) verify you are using the proper environment (e.g. PRODUCTION /
DEVELOPMENT ...) and then run rake db:migrate
5) start typo on a different port then the original typo is running on.
6) Browse to the site by ip:port and verify if everything worked as
planned, and if it did not discuss how it did not work properly, and
if it did work how it can work easier.
... Now let's say you use MySQL.
1) mysqldump your typo database for backup purposes.
2) mysqlhotcopy -u root -p typo typo2
3) fixup the grants if need be so your typo login can see typo2 (if
you use the root account for typo you can skip this step)
4) unarchive the new version of typo, and setup database.yml to see
typo2 and the proper credentials and settings.
5) rake db:migrate
6) start typo on a different port and test it out.
Of course you'll have to reinstall your plugins and themes. I believe
as a standard practice it's best to set the theme to default and
disable your plugins before you do the backup. I don't know if
Frédéric has resolved the technical details of plugins missing and
themes missing and having to goto the admin interface and fix it, or
delve into the MySQL database and disable plugins that way.
But that's a pretty short write-up.
