The "fc" builtin can be helpful here. I like to see my recent history
without numbering, so I can highlight/rerun/store any useful subset of
commands:
# history without command numbers, look for optional pattern.
h () {
case "$#" in
0) fc -ln 1 | less +G ;;
*) fc -ln 1 | grep ${1+"$@"} ;;
esac
}
If I dork up my history beyond belief, edit and reload the whole thing:
histedit () {
x="$HOME/.histedit"
fc -W $x && vi $x && fc -R $x && rm $x
}

You can avoid some history pollution with these settings, at least in
ZSH version 4.3.10:
setopt histignoredups # don't store duplicate lines in command history
setopt histnostore # don't store history commands in history
Other settings I've found useful:
setopt autocd # go to a directory if first word on command line
# is not a command but is a directory
setopt autoresume # single-word commands may resume a suspended job
setopt cdablevars # allows cd'ing to a parameter
setopt correct # try to correct the spelling of commands
setopt csh_junkie_loops # allow short form of loops: list; end
setopt extendedglob # allow # and ^ to be used for filename generation
setopt extended_history # format: <start-time>:<elapsed-sec>:<command>
setopt globdots # don't require leading . in filename to be matched
setopt ignoreeof # don't logout using Control-D
setopt longlistjobs # list jobs in long format by default
setopt markdirs # append trailing / to dirnames
setopt menucomplete # cycle through completions when ambiguous
setopt numeric_globsort # sort numeric filenames numerically
setopt noclobber # don't overwrite existing files
setopt notify # tell me when a job finishes
setopt rcquotes # '' = single quote in single-quoted strings
unsetopt bgnice # don't run background jobs at lower priority
