Tools to help a small shop score higher on the "Joel Test"

Questions #1 through #4 on the Joel Test in my opinion are all about the development tools being used and the support system in place for developers:

1. Do you use source control?
2. Can you make a build in one step?
3. Do you make daily builds?
4. Do you have a bug database?

I'm just curious what free/cheap (but good) tools exist for the small development shops that don't have large bank accounts to use to achieve a positive answer on these questions.

For source control I know Subversion is a great solution, and if you are a one man shop you could even use SourceGear's Vault.

I use NAnt for my larger projects, but have yet to set up a script to build my installers as well as running the obfusication tools all as a single step. Any other suggestions?

If you can answer yes to the building in a single step, I think creating daily builds would be easy, but what tools would you recommend for automating those daily builds?

For a one or two man team, it's already been discussed on SO that you can use FogBugz On Demand, but what other bug tracking solutions exist for small teams?
