Question : vs2008 sp1

I have just bought  vs2008 and does this include sp1?

do i need to uninstall .net framework before install?

Answer : vs2008 sp1

I don't believe purchased versions of Visual Studio include sp1 but if it does, you can check it under the help menu and then select about Visual Studio 2008.  If you are running SP1 your version number will be 9.0.30729.1
