Convert .indd to .psd??

As John said - no way. If a PDF of the file exists, it may be possible to extract separate pages in PS and illustratorand even get partially editable objects, but it will never be the real deal as doing it in InDesign. And then again, even if you are able to edit the data, getting it printed might be another thing, as possibly rasterized elements from PS will never look as sharp and sexy as their vector based brothers could in ID, not tho think of the whole color management dance...

Not really, if the file is an InDesign file. Photoshop is an image editor and handles single pages only. It cannot interpret the layout data of an ID file.
