Fuzzy letters - urgh!

Went to collect my book again today, and I'm STILL not happy with it. The boxes have gone from the images (yay) but the text in the rest of the book is really crap.

As you can see here:

I think it's because I tried to cheat, and just saved the PDFs in photoshop again as CMYK.
The font is also done in photoshop and is RGB.. so today I've been resaving everythign as CMYK and placing that all into indesign again.
Gaaah. I think DPI actually think I'm a retard ... because I am. :(
