Would you recommend getting "Real-Time Strategy Game Programming Using MS Directx 6.0"?

Will the book help me?

Is there any good tutorial with full source, that explains a good, fast tile scrolling function using DirectX?

If you've got a link, please help me!

Unless you're well versed in C++/DirectX I would stay away from the RTS book. It's got some good stuff in it but it doesn't fully explain what you'll need. Try the links page on this site: http://www.gamedev.net/reference/docs/refarticlelistuser.asp?catid=44 . Plenty of info there for you.
