Hi,
1 and 2. Could you contact a developer on this.
Currently with the built in code you’ll need to use a canvas background color to center the images in the slideshow. You can use background color same the page background. Flexislideshow style doesn’t center images currently.
3. Clicking on a work type category will display the work type category archive galleries. This is by design.
Following is from the demo
