Hi, This book is great and gives you everything you need to know about getting started with blogging. http://www.amazon.co.uk/Blogging-Creatives-designers-crafters-contacts/dp/1908150262/ref=sr_1_1?ie=UTF8&qid=1363794535&sr=8-1
Once you've chewed through that one, it's great to slowly introduce your brain to web coding. This book is super friendly and really useful. I got onto it from another Mumsnetter and loved it.
