You say, you uninstalled everything including SQL server. Later just installed VS2008 and you still seek for SQL server 2005?
SQL Server 2005 has a separate installer and it will not be installed along with Visual studio. if you want it then install it again.
UPDATE:
Post install of VS2008, after you install SQL, if management studio is missing, follow the steps:
1. Find Microsoft Sql Server 2005 in the Add/Remove Programs (Control Panel)
2. Choose "Change Installed Components"
3. Right-Click on "Client Components" and select "Not Available"
4. Click Next, Next, and then "Install/Finish" - This will remove the client components that were installed with Sql Express 2005 and Visual Studio 2005/2008
5. Now, run Sql Server 2005 Setup
6. Click Next, Next... Then click the checkbox "Workstation Components, ...." and then click Next again, and eventualy Install.
7. If you look under your START MENU > PROGRAMS > MICROSOFT SQL SERVER 2005 folder, you should now see that the Enterprise Manager for Sql Server 2005 is now installed.
