I would replace single picture with 2 to 3 pictures that are vertical possibly over the headboard. Depending on the size, display them across your headboard so that they span further than the current picture, say across the headboard but inside the shelves. In addition you might want to consider some sort of lighting that you can attach to the headboard that you can direct down rather than thinking of table lamps. I think the shelving can work, but for me would be collectors of things and never looked very nice. If you're different than me maybe you could start with something low on that top shelf with just some small things on the other ones. Good luck

An electrician can hard wire it and run the cord out the base. Just turn the cord hole to back and silicon closed. Or get custom made

I would call it a glass bowl hanging light. This company sells them as new replications. I'm sure yours would be worth more because it is original. https://www.fatshackvintage.com.au/products/chateau-glass-hanging-bowl-light
