James,
You appear to have a very clear idea of the visual feel you want to put across. Therefore, you may find it easier to more effective for you to look through the portfolios of those interested in doing this work, so you can see general visual style.
The references to the kind of thing you like are interesting, so I'd suggest that who ever does the design work, starts with a strong branding of the night, aside from the posters.
Does you printer specifically ask for PSD, that seems a possible bizarre choice to me.
