Setting a new development environment for an IT firm

Dear Sirs,

I want to set the development environment for an IT firm, we will be using the following technologies:-

1. Asp.net MVC web application.
2. Entity framework
3. IIS
4. SQL server 2008 OR 2012. 

As I came from academic background I use to do my work using visual studio 2010 & 2012 express for web.

But the requirement for the development environment is:-

1. To have  a single access point that allow multiple developers to work on the same application at the same time
2. To have versioning and release management for the web application
3. To have a bug tracking tool. 

So I am thinking of the following approach:-

1. To use the Visual studio professional 2012 for both the muli-user development, versioning control and release management.
2. While for the bug tracking I am seeking to find an open source bug tracking such as bugzilla. 

So can anyone advice if my approach will be fine?

Best Regards
