Best I could find out is that Microsoft Visual Studio 2005 Academic Professional Edition is a boxed set. Did it not come with any instructions? Have you checked the disks for readme files or other text files that may provide instructions?
1. SQL Server 2005 Developer Edition 64-bit CD1
2. SQL Server 2005 Developer Edition 64-bit CD2
3. SQL Server 2005 Developer Edition IA 64-bit CD1
4. SQL Server 2005 Developer Edition IA 64-bit CD2
13. SQL Server 2005 Developer Edition 32-bit CD1
14. SQL Server 2005 Developer Edition 32-bit CD2
If you have a 64-bit machine choose disks 1 & 2. Disks 3 & 4 are specific to the Intel Itanium processor series.
7. MSDN Library for Visual Studio Stystem Disc 1
8. MSDN Library for Visual Studio Stystem Disc 1
9. MSDN Library for Visual Studio Stystem Disc 2
10. MSDN Library for Visual Studio Stystem Disc 2
11. MSDN Library for Visual Studio Stystem Disc 3
12. MSDN Library for Visual Studio Stystem Disc 3
These would be the help files. Try using Windows Explorer to determine which set of 3 discs is for 32 and 64 bit machines.
5. Disc 1
6. Disc 2
Presumably, these are the actual Studio programs. Studio installs in about 3GB so you probably need both disks. Use Windows Explorer to determine which bit version you have. You might be able to get an indication by the file names (setup32, setup64, etc)
If the actual program files are 32-bit, I would stick to the 32 bit versions of SQL and the MSDN library.
Good luck.
