I need to do this sort of thing frequently since I'm always making plans for furniture piece. I do use LayOut which makes it much easier but much of what I do you could do with Make.
First, you need to make sure you are using layers appropriately so you can make parts invisible when you don't need to see for a given scene. You can make copies of the components and shift them off to another part of the model space to create other views like 3-views of parts and exploded views. Here's an example from a recent plan.

Between layer management and camera position, I can show exactly what I want to show for each scene. It's much easier to fine tune the view in LayOut but in your case, export the scenes as images. Then import those images into your document. You can control the size of the images during import and you can use an image editor to crop the images if needed.
FWIW, it is totally inappropriate to scale your model to make it look larger. You can zoom the camera to look at a smaller portion of the model if needed but don't use the Scale tool. That invites all sorts of problems including incorrectly displayed dimensions as you mentioned.
BTW, doing this with SketchUp Make and some other document creation software such as MSWord is time consuming. Revisions are especially problematic. If your time has any value at all, you would be wise to spring for SketchUp Pro so you can use LayOut. In the grand scheme of things the cost is relatively minor compared to the time you'd save in making the plans so you can get to the shop and start building.
