If you actually intend to print this larger than 5x7 cm, then you need to increase your resolution first. It will still look crap if someone opens the PDF/image and views it full screen, or prints it on A4. If this is the intended size, then your image will print ok. Your image, at 300 PPI (good quality), can be printed at a maximum of 5x7 cm. on a piece of A4, in a magazine, etc.) you want to squeeze at least 300 of those pixel into each inch (so that is, 300 pixels per inch, or PPI for short) or else it will look pixellated (or blurry). If you create something that will be viewed up close on print (e.g. a poster, each individual pixel will be HUGE and very visible (like if zoomed when viewing it on screen).

Try zooming in while in Photoshop to see what I mean (it is the same thing that happens if you try to zoom in on raster areas of your PDF in Acrobat). Now, obviously with a raster image you have a finite resolution. Use maximum JPEG quality in the PDF (or if saving a JPEG directly).
The only solution to retain appearance - keeping it just like it was in Photoshop - is to flatten the image first, so the whole thing remains an image on export (so you might as well save as JPEG). This ofcourse can lead to shifts in appearance, especially where vector/text elements end up partially beneath areas that has to be rasterized. However, any Smart Objects will be rasterized (like what they are when you look at the canvas in Photoshop). What is happening when you generate a PDF from Photoshop is that Photoshop sais "oh shit what is he doing" and desperately tries to retain text as text and turns shapes layers into raster fills with clipping paths. It should all have been vectors in Illustrator/InDesign.
There is absolutely nothing in your design that would need to be raster.
Consider downloading a trial of InDesign and Illustrator. Now, if you only have Photoshop, that sucks. in InDesign (or Illustrator) and export a proper print-ready PDF from there. You should be setting all your type, etc. Photoshop is for raster images (like photos, etc.). I strongly advise against creating print-PDFs in Photoshop.
