The free Seaside book and also the free Pharo by Example book are great ways to learn MVC. The only downside is that after using Seaside and a Smalltalk environment, you will probably be dissatisfied with not having such awesome features available in modern tools. :)
Edit: It looks like there is a new Pharo book that covers more advanced topics! http://deepintopharo.com/
One should also note that Seaside is likely the direct inspiration for Arc's (i.e. HN's) use of links that reference stored server-side closures by ID.
