1. Part of the tables that create the Galleries are hardcoded. So it's tough to generate additional space. I suggest you experiment with the TD's (but I don't gurantee that it will work). I think this is a good suggestion for an enhancement/new feature, please make sure you add it to the DNN Bug Tracker.

2. Color and Link styles should be easy to modify though. They are defined either at the theme file. If not, they might be inheriting from skin.css or default.css class definition.

3. All classes used by the module should be apparent in the generated page source. You can navigate to them using IE Dev Toolbar or the FF equivalent DOM exploration tool.

A better questions is how can you have *less* space between the photos? Currently there is a huge vast expanse of empty white space between the photos.... it looks like this might be changeable in controls/controlviewer.ascx and/or the themes css, is this correct?
