When i have figured out how to make a hard-grid/layout within InDesign,
By @NM PDI
InDesign has two types of grids: baseline and document. From what I am reading, your will want a document grid. There are three steps:
1. View the grid: View menu > Grids & Guides > Show/Hide Document Grid
2. Set the grid: Preferences
3. Use the grid: View menu > Grids & Guides > Show/Hide Document Grid

In addition: to edit the images in Photoshop:
In InDesign: right-click the image in the layout or Links panel
Edit in > Photoshop
In Photoshop: edit, save, close image
Return to InDesign. The image is updated
If you start the edit from InDesign, the update is automatic. If you start in Photoshop, updating links is a separate step and is done in the Links panel.
