Yes, with the shapes button, by selecting the rectangle. If you activate the snapping, the drawing tool will snap to guides, objects and grid.
The image disappeared because you have a white fill for the rectangle. Just change the »Color« to »None« in the »Properties«, and set the line to black (or any other color which you have to define first in the -> Menu -> Colors and fills -> CMYK.
For the background, you can draw a rectangle and fill it with black, then convert it into a master page which you have to apply to all pages. Or you can copy the first background on its own layer and paste it at the same layer on all pages. It is simple and fast.
Image frames: If the images have different sizes, there is no way around drawing a rectangle around each image. You can speed it up by copying a rectangle and modifying the size for each image.
I don't know of any other software where you can add frames for all images with one single click. Remember: Book design and printing is not a »point 'n click« task. Book design and making is a sophisticated task which requires a lot of training, expertise and experience. Forget the »YouTube University« where everything is finished in 3 minutes. It is not a coincidence that book designers, typesetters, book printers and book binders are old professions which require (at least in Europe) a 3-year training for the first level, and a 10-year training, expertise and experience before you can apply for a master exam and title — separate for each of the mentioned professions.
Just because there is a software, and you know how to operate it, it does not mean that you know what you really should do before you even start your computer.
