You need not download and install sql developer software separately, that is integrated with oracle 11g. You need to download and install the version as per your OS and system configurations. You need not install any other software to have your database running. Using sql developer software is optional as you can run your queries from command prompt itself.

You need not install any of those to install oracle and run the database. You need read those documentation carefully and understand what it says. If you want to run oracle database , why need to bother about .net or c++ or cobol.
