I believe history is always enabled.
Look at the section of the man page that mentions HISTFILE.
For the arrow keys, in your login profile
export ENV=$HOME/.kshrc
in your .kshrc add this:
case $- in
*i*) #interactive ksh
# This stuff lets the arrow keys work in an xterm...
set -o emacs
alias __A=`echo "\020"` # up arrow == ^p == back a command
alias __B=`echo "\016"` # dn arrow == ^n == down a command
alias __C=`echo "\006"` # rt arrow == ^f == forward a character
alias __D=`echo "\002"` # lf arrow == ^b == back a character
