How do I Import Indesign files into Photoshop without loosing to much detail in the Type?

Grayscale will reproduce correctly in InDesign if you take some precautions.

There is no grayscale color management in InDesign or indeed outside Photoshop at all. So you have to use a grayscale profile in Photoshop that matches the intended output, otherwise you get tonal shifts. If there was grayscale color management in InDesign that wouldn't be necessary, but there isn't and it is.

A grayscale file in InDesign will simply output to the K channel, the black plate.  So you need to know the CMYK profile that will be used on press. You need to know that in any case, so just ask the printer if you don't know.

You can then set up Black Ink <CMYK profile> as working gray in Photoshop. Once that is done, you can pick that in Edit > Convert to Profile, and the numbers will be correctly converted and the file will be correctly reproduced in InDesign.

In the working gray rolldown, navigate to the CMYK profile used:

"I know I should porobaly just be using InDesign for such jobs, but i'm not as well versed there and also have bumped into issues there regarding greyscale images."

Yes, you should be using InDesign, then choose File > Place to properly place a link to your images.

Using the wrong tool for the job is never a good idea.

You can't import a native InDesign (.indd) document into Photoshop.

The usual workflow is to Place a Photoshop (psd) document into an InDesign document where you add text etc.

What are you talking about? How are grayscale images a problem in Indesign? 

How did you place the thing in Photoshop – a placed pdf, rasterized, copy/paste, …? 

Either way it would likely not produce vector output for the type so it should be a non-starter if you are serious about your work. 

That said it looks like you did not anti-alias the object.
