Is there a " RedBook" for british coins? What about composition and denominations?
There are several options. The most widely quoted is probably the catalogue put out by Spink, Coins of England and the United Kingdom. It covers the entire 2100-year spectrum of English coinage: Celtic, Roman, Anglo-Saxon, Vikings, Normans, English hammered and English/British moderns.
Becoming more popular, and especially useful if the ancients and mediaevals aren't your thing, are the Rotographic books. Collectors' Coins GB is their main British catalogue. It's cheaper, but smaller and generally less informative as far as background stories go.
For general information on the series, there are websites. Tony Clayton's website is often near the top of Google searches, for good reason: it's been around for ages and has lots of good basic info on British coins.
What is a good set to start with for someone new to the whole idea of collecting foreign coinage?
Besides the usual date sets and type sets, the sheer breadth of English/British coinage allows for other different kinds of collections to form. The coins of Queen Victoria and her son Edward VII are often considered the high point of British coin design, and collecting a type set is not too expensive. An alternative method is collecting "one from each monarch". Early hammered coins were struck at a multitude of mints and some try for a "one from each mint-city" collection.
Are there "danscos" or other albums made for organizing?
I don't know about Dansco, but Whitman made (but as far as I know, no longer makes) push-in albums for Britain and several other British Commonwealth countries. But it's my understanding that "set collectors" aren't as common in Britain as they are in the USA, so there's little local demand for set albums. The only "set albums" you're likely to encounter from anywhere in Europe are for the euro coins.
Hope this helps.
