I would recommend having a gander at this StackExchange post.

Javascript and W3C validity?

I would always recommend not being too obsessive about W3C Compliance, especially when it comes to Javascript. Since you want to use a Transitional doctype as well they are much more loose. I'm not saying don't go for full compliance, just don't lose any sleep over it, if it works in all browsers then excellent, what more do you need!
