52 sheets of paper?
If you still want to saddle stitch, I wonder if you can use “hi-cap” staples that can hold more pages.
Either way, definitely get a bone folder (like this one) so you can really flatten those folds. My mom was a career librarian and gave one to me when I was in college (30 years ago). It’s one of the most useful tools I’ve ever owned.
i make a new collage zine every month! here's « ONE MORE THING », the zine for january 2022! it's a miniature booklet measuring about 3 inches in height, printed on a very soft, pliable paper and finished with an odd-size insert & rounded corners! the eight collages were all made to-size -- quite tiny -- with threads of text running throughout. year of the tiger!
also made a new half-size zine, « MONO », which collects some of my favorite monochromatic collages from 2021, and have been working on some stickers & confetti made from zine trimmings (the 'don't waste paper' ethos!)

Layout: Get an inexpensive software package that does proper help with booklet layouts and imposition ordering (you can look that up). I recommend Swift Publisher. It's cheap, but quite effective. Swift Publisher
Graphics: If you're using Inkscape, you might want to couple that with Gimp. It easily reads the SVG files Inkscape creates and it's free. GIMP
PDFs: Most computer operating systems will allow some way of printing to PDF file format. If not, most decent software should have a PDF Export option.
I bought a cheap guillotine trimmer to clean up edges after I staple my zines together. A lot of zines I see at shows don't bother, so I don't think many people really care, but I like the clean edge look. Just give yourself a little extra margin so you won't slice into your words/art.
It really depends what your desired outcome is. 'Making Books' is a pretty good guide to equipment, formats and binding: http://www.amazon.co.uk/How-Make-Books-Esther-Smith/dp/0307353362/ref=sr_1_1?ie=UTF8&qid=1433083213&sr=8-1&keywords=how+to+make+books I think that could be the kind of stuff what you're going for, when you're talking about stuff that looks like it could be in a bookstore.
