Mark Boulton's A Practical Guide to Designing for the Web (Five Simple Steps) http://www.amazon.co.uk/dp/0956174019/ref=cm_sw_r_tw_dp_f-cg... is also a good start.
There are the usual suspects such as Nettuts, Smashing Mag, Core77, Creative Review, Design Observer (though that's more intense).
For web typography, try http://kaikkonendesign.fi/typography/ and the older (but based on a lauded print book for print type design) http://www.webtypography.net/
Just for the insight into the nutty world of type design, I like the MyFonts newsletter: http://www.myfonts.com/newsletters/cc/201301.html
If you want to get more into IXD, Cooper has a good list: http://www.cooper.com/journal/2013/01/self-study-interaction...
