I would definitely recommend the following books:

- How Breakthroughs Happen: The Surprising Truth About How Companies Innovate by Andrew Hargadon

- Micro ISV by Bob Walsh

- Smart and Get Things Done by Joel Spolsky

- 4 Hour Workweek by Tim Ferris

and here is one that I used in school that has great intro level information on a variety of topics.

- The Portable MBA in Entrepreneurship by Andrew Zacharakis (check the spelling)
