It's been said already Blue Velvet, but I will reiterate just in case.
1.) you can have the Application appear in all spaces. So that when you change spaces the app window will always be there.
2.) It won't change your dock, but there are apps that allow you to have more than one dock, and there is always the Stacks option which I have adopted. Keeping my trivial stuff in Stacks, and the professional stuff in the dock.
3.) I have actually found spaces useful even with large displays. My home machine with 23" ACD has spaces active, but my 17" MBP doesn't simply because I won't have too much windows open other than FCP and Aperture and maybe Photo Mechanic.
