Now next thing. I am not sure wheter it is good idea to fill in normal photos. But where do I get vector graphics like this pinguin instead?
I would be fine buying them (if price is okay), but where?

There is an Inkscape menu entry - import clip art. Does not work here but should take you to: https://openclipart.org and lots of penguins there if you search.
You have to look at each example for license terms, that one free for non-comercial use.
Clip art used to be a favourite for computer mag cover CD's. Had to pull one out of my archive (junk box) a couple of days ago. http://i.imgur.com/6Jyz5Qc.jpg There are similar collections on ebay for little more than cost of postage.

If I draw a rectangle and type in the size, let's say 150mmx150mm and then switch to the tool, which helps with positioning the size of the rectangle changes to 150,26x150,26mm. If I change it within this menu back to 150x150 and then go back to the rectangle drawing tool, then the new size shown within this menu is 149,735x149,735.
How can I fix this?
2. If something looks good as pdf, does this mean that it can be printed with good quality? for example:

Sorry, pressed the wrong button.

Gimp works in pixels. There can only be whole pixels, not fractions of a pixel. If you say 150mm then Gimp will convert to pixels and round of to the nearest whole pixel. That is not exactly 150mm
2.
Check with your printer as to what their requirements are !
How large is the print in mm? How many pixels is the image? Then calculate dpi. 300dpi will give a good print.
Gimp works in RGB. The printer works in CMYK. A colour conversion takes place. There can be some variances in colour.

Not sure how you are moving between tools and keeping the selection settings but
As Blighty wrote, Gimp works in pixels, so there are rounding errors when a size in millimetres does not correspond to whole pixels.
With default settings you are working with a mixture of units. The canvas resolution typically set in pixels-per-inch but your dimensions are in millimetres.
Create a canvas 150 mm x 150 mm but use millimetres for the resolution (1) in this case 6 pix-per-mm The canvas is 900 x 900 pix and Gimp gives a resolution of 152 pix-per-inch.
Change the resolution to 152 pixels-per-inch and the canvas size is now 150.06 mm x 150.06 mm or 898 x 898 pix.(2)
Of course the correct ppi to use is 152.4 but try explaining that to your printer who will probably use 150 ppi anyway

Using PDF for publishing is usually not a problem but what you put in, is what you get out.
Text & vector graphics are no problem since they get scaled accordingly, If any bitmaps are embedded, these need to be suitable resolution, if they get scaled up or down a great amount they will degrade.
Your PDF is card is not a large print 60mm x 90mm @ 300 ppi It will look OK when printed.
If you compare the embedded image (pulled it out with a PDF editor) you see that scaling a 2000 x 1181 pix image down to fit in the card whether you do it manually or let an application do it for you does give a little fuzziness, but not worth correcting. Be more aware of scaling an image up.

In Inkscape, the object has a fill and a stroke. The sizes you see are for the bounding box that encloses both fill and stroke.
Draw a 150x150 rectangle with fill but no stroke. It will behave as you are wanting.
Now add a stroke. 50% of the stroke will fall inside the rectangle, 50% outside. So the size of the bounding box increases to accommodate the stroke.
Okay, more general question. I have this card with an optial illusion. But unfortunately the illusion seems to only work if the image is very large. Do you know a similar illusion which works in smaller size?
