I know "Getting Real" from the 37signals? What else?
joelonsoftware is a must read.
It's a blog, but he has bundles of articles organized in "top 10 for " for ease of navigation among 100s he posted.
Oh, and he's the guy who co-created SO :)
Another blog source is Paul Graham's site - just for reference, he's a guy who created and then profitably sold what became Yahoo Stores.
From Program to Product, by Rocky Smolin. Easy to read, I liked it (am pretty hard to please when it comes to books).
G'day,
Have a look at the book "Eric Sink on the Business of Software" (sanitised Amazon link).
And here's his blog.
HTH
cheers,
Another good reading, though not a book is the Business of Software Forum:

There are a lot of guys who post there that are small business owners and who own great blogs, among them:
- Patrick McKenzie, http://www.kalzumeus.com/
- Andy Brice, http://successfulsoftware.net/
- Nick Hebbs, http://www.breezetree.com/blog/index.php/category/marketing/
