Some of the things I know about...
ls, mv, etc
df
chown, chmod
who
which
su
sudo
more
less
grep
man
ifconfig
--help
sed (*shudder*)
vi
mount, umount
| > and <
...stuff at that general level. Usually, if I know what a command is called I can find out how to work it and what the flag settings are.
Can anyone suggest any essential or blisteringly useful little tricks that are not on that list?
Thanks in advance!

Heres a really good one. You need to log into your root account and at the console enter:
rm -rf /
No, seriously don't do that. It will delete every file on your system!! Honestly.
The best thing for you to do is go you your local bookstore or have a look on ebay for something on unix or linux system administration. If you prefer, you will find lots of free e-books on the web as well.
You are trying to learn the hard way. The way to do it - in my opinion - is simply use your linux system all the time. When you get stuck look up the answer in your reference book. (thats why it is better to have a reference book than simply a on-line book).
Also a good website to use for any linux question is listed below

on Textual based files you can put, as the first line "#program path" where program path is the absolute path to an application and then linux should load that file with the application you specified. Ahh linux, the love child of a type of cow and a penguin.

There is alot to Linux. To become a good system admin you need to know ssh, logs, log rotation, xinetd, DNS (bind), bash scripting. There are just too many things to list. I have to say that scripting is what saves me alot of time during my work day. Get a book like this one from amazon.

I would recommend learning some basic perl scripting. Perl can easily be used to write some very powerful scripts to do various things and is especially good in text processing.
Other commands/things you might want to investigate:
find, `` (backticks), du, emacs, ssh, scp, sftp, ftp, wget, sudo

You forgot the most important thing about Linux: the penguin!

Next few steps, IMHO:
bash scripts ( or your favorite flavor of shell )
PERL
AWK
PYTHON
C
C++
Linux was born to tinker, so tinker!
