Silverlight 4 in action which comes from Pete Brown who works at Microsoft.

You can never go wrong by heading directly to the Silverlight site which has a learning section specifically geared towards coming up to speed with Silverlight, advanced topics as well.

If you reside in a state where the SL tour comes to town and have the available funding; you could get an intense 3 day course on varying SL4 concepts. It is put on by Shawn Wildermuth who is fairly prevalent in the SL community.

Erik Mork via Silver Bay Labs provides varying videos which touch on a range of topics and have proven beneficial to me in varying scenarios.

Silverlight is a sub-set of WPF, so try looking for WPF programming tips!
