[Talk-gb-midanglia] mapnik style sheet

I finally got round to revamping my old PC (and was pleasantly surprised at
how easy Ubuntu is to get going from scratch).
After considerable head-scratching, it is now rendering a UK snapshot from
OSM data using mapnik and serving the tiles via apache (just locally).
However, the rendering that I see is not the same as on the OSM slippy map
- with problems of very strange changes of things like road colour when I
zoom in beyond certain levels. It looks (bear in mind I know virtually
nothing about how manik rendering really works!) as if the road casing is
being drawn but not the fill. eg trunk roads appear the usual pale green at
low zooms and suddenly go very dark green as I zoom in. Similar effects on
primary roads (which go dark red).
I wonder if the osm-template.xml template that I got from
is correct / up to date? Or am I likely to have some other issue?
I have played around, hacking the resulting OSM.xml, and I can certainly
change the map appearance radically (!) but my, as yet, somewhat random
hacking is a very slow learning route.
If anyone has any knowledge or can point me at rather more digestible
sources of information than any of the many that I've read so far, I'd be
