In reply to SandstoneYorkie22:
I've not read the rockfax book but the other two are good, the mountain training book being the most UK specific.
Setting up top roping style anchors isn't particularly common in the UK and doesn't really differ from summer unless you are using winter specific anchors.
I've no idea of your experience level, but my advice to anyone starting winter climbing is to find someone experienced to learn from, this could be a mate, club member or a paid instructor. There are lots more skills needed to move around the mountains safely in the winter than in summer, such as navigation, avalanche awareness and planning, crampon technique, ice axe arresting and that's before you even start climbing.
