For the placement (and desktop number, etc.) look into "devilspie". The gnome WM (metacity) can't even do this, so you have to resort to another application to get it done. There's info around on how to set it up.
To add applications at startup follow the instructions from the other poster above. You will need to add devilspie there as well
