What blogs and books with the potential to have a noticeable impact on a small business' success do you recommend ?
PS: This is not about creating a "complete" list - time is scarce: quality over quantity!
On reflection, the books I got the most out of that actually shaped my behaviour are...
THE PERSONAL MBA, JOSH KAUFMAN
Was blown away by this. Couldn't believe how much stuff I didn't know about. It covers everything you've asked about and more...
It's also written a bit like a Software Patterns/Recipes book, which I love.
I've read the MBA book about 5 times.

PITCH ANYTHING, OREN KLAFF
You'll hate reading it. It will make you cringe. It's uncomfortable.
But it changed my attitude to business, my products, and deals a LOT. Which is REALLY important.
Applying some of these techniques had amazing results in any dealings with 3rd parties (sales, partnerships, deals). That's because I'm a softie engineer, not a battle-hardened business man. I still read this before attending any significant meeting.

HOW TO BE THE LUCKIEST PERSON ALIVE, JAMES ALTUCHER
Covers everything in one way or another...
I keep coming back to the epic rule list in this book. I keep ignoring them in business, then learning the hard way that the list is right. He shares his failures and successes in a humerous way.
It's a real down-to-earth, eye opening book.

OTHER
I'm reading Lean Startup, and have read Made to Stick, Letting go of the words, Ignore Everybody, Spin Selling, and tons more. All good books, but the 3 above were the biggest impact for me on all levels.
Obvious starting points are http://www.kalzumeus.com/start-here-if-youre-new/ and http://www.kalzumeus.com/greatest-hits/
I'd definitely suggest signing up for his Email list too at the top of that site.
Also, Made to Stick: Why Some Ideas Survive and Others Die, by Chip and Dan Heath. This helped create more effective and compelling content. It's very high-level though.
