well my first attempt came in at the same length as japhy's (109 chars, 98 excluding the setting of $h and $f): 
($h,$f)=@_;for(1..$h){print' 'x($h-$_).($_==1?'*':join'',map{rand>$f?'
+=':qw(* 0 @ +)[rand 4]}1..$_*2-1)."\n"}

... so i had no choice but to cheat. =) the following satisfies the rules strictly speaking, but only uses '0' as a decoration. it's 91 chars (or 80 excluding the setting of $h and $f). 
($h,$f)=@_;for(1..$h){print' 'x($h-$_).($_==1?'*':join'',map{rand>$f?'
+=':0}1..$_*2-1)."\n"}

of course japhy's entry could be modified similarly, thereby bringing us equal again.

oh well, as they say, cheaters never win.
