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:
I'm currently using SVN but I've generally had a lot or problem with checkouts to a network drive on a dev server. There tend to be locking issues that require a lot of fishing around to fix. It may be that using the WebDav access method, would ease some of these problems, but I haven't experimented yet.
Any of Bugzilla, Trac or Fogbugz will help you with your bug tracking, and each offer an export feature, so you can always change your mind later on. Also, if you can get your team to fully buy in, time management software can also be handy for post-mortems, etc (if everyone is motivated to fully participate.
