The Trim is the InDesign page size.
The Type area - this is the margins - so you'd want the type area to be be this centred on the page - all your text should be in this area and not outside it.
Bleed size refers to how much bleed. Any images/text or other items that are going to be outside your type area need to extend out into the bleed area.
