I think it's books you need to be rereading rather then looking for websites.
How out of date is your contract book, I'm guessing maybe about 5 years?
You could get a Nutshells for a quick update but if you're doing a job which involves contracts and they expect you to know the law then I'd say it's back to the books.
You could always see if there are any courses about as there are always CPD courses on for lawyers to keep up with their development.
Try people like BBP and Altior or College of Law.
They can be quite pricy though so I guess it depends on how much your new employers think you know.
