i'd recommend bind mounting the filesystem/directory where these files 
are located to your chroot (example if it is home directory):
put the following line to your /etc/fstab (modify to fit your setup)
/home   /var/chroot/ia32/home none  bind        0 0

then files should be accessible in chroot. for the parameter passing, 
follow the instructions in the amd64 howto:

create a script called e.g. do_chroot in your /usr/local/bin (modify 
accordigly)

------------------------
#!/bin/bash
# execute application from chroot in a way that is transparent to the user

ARGS=""
for i in "$@" ; do
  ARGS="$ARGS '$i'"
done

exec dchroot -c ia32 -d -q "`basename $0`" "$ARGS"
------------------------

now, create symlinks in /usr/local/bin for all programs you execute from 
the chroot, i.e.

ln -s do_chroot oowriter
ln -s do_chroot oocalc

put /usr/local/bin to your path. now, executing oowriter filename should 
do the trick. you should now be able to set it up in gnome or whatever 
you want...
