Your additions for the nmapplet and lxlauncher were good. Those are things I don't use (do it by hand) so I don't consider them. You could update the OP for N800 users to use the without-recommends for apt, that way you don't get the GDM login.. they can reboot and get to LXDE. The problem with N800 right now is that AFTER you reboot into LXDE I haven't found a decent on-screen keyboard that works right in LXDE =-\. NOTE: don't rename the xmodmap to Mer-xmodmap... install it to /home/user/.Xmodmap - if you used the full "apt-get install lxde" then gnome/gdm will automatically load your xmodmap file when you login. I dunno if it works at the GDM screen.. but I do know it works after you get into LXDE.
