Suggestion:
o Start with bash and zsh. I'd suggest you'll generally find that
these are advanced shells which supercede virtually all the
functionality of precursor shells, including the Bourne shell line
(sh, korn, posix-compliant, bash, bash2) and csh line (csh, tcsh,
zsh). For userland, you're most likely going to find that bash
and zsh are going to have features you really, really like.
You may also want to look at a few alternate shells, for special
purposes.
o ash is a lightweight shell, useful on rescue disks (though
last I checked, Tom's Root/Boot seemed to be running a bash-like
shell). As standard shells have bulked up, lightweight shells
are finding a place for rescue or limited-storage situations.
o sash is a "secure" shell -- it contains built-ins for a whole mess
of what are normally system commands. It is also (usually)
statically linked -- it doesn't require external libraries. This
makes it useful as a rescue shell or for exploring a system which
is suspected of being compromised.

See the BashPromptHOWTO for equivalent under bash.
In my .bashrc
# Following sets prompt to [EMAIL PROTECTED] dir], and puts the full
# [EMAIL PROTECTED]:/full/path/spec in an xterm title bar.
function proml
{
case $TERM in
xterm*|rxvt|eterm|wterm)
local TITLEBAR='\[\033]0;[EMAIL PROTECTED]:\w\007\]'
;;
*)
local TITLEBAR=''
;;
esac
PS1="${TITLEBAR}\
[EMAIL PROTECTED]:\W]\
\$ "
PS2='> '
PS4='+ '
}
proml
unset proml
export PS1

Start with the best feature: completion. There's a script,
/usr/share/zsh/functions/compinstall. Source that
(". /usr/share/"), and, voila, a menu for configuring the
completion system.
Badass, I tell you... ;-)

Maybee it's tcsh... don't know, works for me, sorry.

Closer is glob_complete (setopt globcomplete).
But probably not exactly what you want... it expands the word in the
command line and steps through the completions via TAB.
The original *.html is gone, so pressing ENTER would jsut deal with
one.
Though, maybe that is what you want. But probably not. OTOH,
mentioning it on zsh-users might bring a surprise (the zsh folks are
always willing to make zsh even fancier ;-) (zsh-users is gated into
zsh-workers).
Bye, J
