You could use aliases for some of this.  Take the command you want to
use later, copy it verbatim, then make a line like this in your
.bashrc file (at the end, to be safe )

    alias chrootResolv="sudo ln -f /chroot/breezy/32bits/resolv.conf
/etc/resolv.conf"

(where chrootResolv is the name of your "new" command)
load the new .bashrc with

    source ~/.bashrc

(or open a new terminal)
and run chrootResolv to build your link...

You can also use the .bash_history file for a lot of what you want. 
Dan Haskell already mentioned using ctrl-r (which I *strongly*
recommend also -- you can just keep hitting ctrl-r to get to what you
want, at which point hit enter to run it, or use the arrow keys to
move the cursor and make modifications).  There are other tricks also,
though:  command history (up/down keys scroll through recent
commands), and you can grep the .bash_history file directly, if you
want (or cat, tail, less, etc...)

At one point I put it in cvs, and added the ci/update commands to my
.bash_login / logout files, but that became problematic..

If you hit tab twice (eg: /etc/ <tab><tab> ) you get a list of all the
possible completions, from which you can narrow the search.
