I have loads of books / sites on web design and little tips and tricks but, if you don't mind forking out for it, I would suggest "How to WOW - Photoshop for the Web" by Jan Kabili & Colin Smith.
Particularly if you have PhotoShop CS (8.0).
It will enable you to do the whole thing in PhotoShop / ImageReady and possibly some things you haven't even thought of yet.
I used Colin Smith's web-site 'PhotoshopCafe' tutorials when I started using PhotoShop so, when I saw his name, I bought this book and it's been very inspiring.
