Two that will cost but are decent:
http://www.microsoftelearning.com
Microsoft eLearning has courses which are relatively inexpensive that introduces you to SQL Server 2005. They used to be free, but I don't believe they are any longer.
http://safari.informit.com
Safari has a number of IT books online (including new ones) which you can put on your bookshelf and discard a month later. There is a small monthly subscription fee. There are some good SQL Server 2005 books available.
