Hey s,
Career advice - hard to say, I was a builder by trade but changed tack due to a recession, then managed supermarkets for 8 years before getting into IT!!! An IT degree sounds like an excellent base to build on, but IMHO having your own web site and/or other programs to show potential employers would carry a lot of weight when you start looking for work.
As far as javascript goes, I've read the wrox beginning & professional books & found both very good.
I haven't spent much time with online tutorials, but find forums such as this one a great source of knowledge & spend quite a bit of time trawling the net for ideas & looking at how other people do things, these two sites are a couple of my favorites...

Loads of luck,
