Well careful in what you’re saying because margins are strictly just guides. So no, you do not have to set them, but they do help make a consistent, attractive layout.
Bleed however is what happens to printed images and color when it runs off the page. You ‘bleed’ the artwork or color. In InDesign the bleed is also referred to as a guide. You don’t need to set the bleed guide if your document has no art bleeding off the page.
However if art *is* bleeding off the page, it is imperative you set the proper bleed guide. If you don’t, InDesign will ignore the bleeding when printing or RIP. It’s not a major worry as you can change the bleed guide setting in the print dialog too, but it makes it easier to do it once in the document settings and be done with it.
