Printing and etching
Played a few more hours with wire widths and finally printed the thing on Press'n'Peel. Every site and reference said that Press'n'Peel is easy to use and most people succeed at first. Well MOST maybe but not ALL I can assure you.
I corrected the PCB before etching with Patex glue. Not a very main-stream method (to say the least) but I was too impatient to wait till Monday to buy some correcting pen or something. This glue (Patex Repair Extreme to be precise) forms a somewhat flexible greyish substance after drying - but more importantly it is not etched away (trivial) and it's easy to remove.
Etching went like a breeze, no problems there. I used Fe(3)Cl. Cannot comment on ratio of water to FeCl and such; I simply dropped FeCl into water until it seemed OK.
