I have an old copy of 'Dayskipper' by Pat Langley-Price. It isn't that brilliant, to be honest, and it seems to make fairly simple parts much more complicated than they actually are but it is all there.
It is important to do lots of worked examples and get the answer EXACTLY correct. OK, at sea, you are not really interested in much less than 2-5 degrees heading but only by doing the examples exactly will you be sure that you got the right method!
Don't know about the charts. I've never had an Admiraly Touchchart. I use a very soft 6B pencil and a soft rubber (that's an eraser for the benefit of our American cousins  ) Artists' putty rubbers are excellent, too, as is a damp J Cloth at times. ISTR that Langley-Price came with a practice chart? I also downloaded a Channel Islands real time simulator which was really useful to get my hand back in from a long time away from the sea and lots of aero nav in the meantime. I just kept bashing away on difficult approaches on the simulator until everything fell into place.
