Freelance Advisor has podcasts and regularly released articles to help freelancers and contractors. It's well worth a look - we would say that as some of the writers are also in the Farm, so you know you're getting top quality advice!
The Professional Contractors Group has lots of good advice and services for freelancers. Including a Guide to Freelancing covering many tax issues and information about going Limited or starting a Limited Liability Partnership (LLP.)
