First off, I suggest you contact HP sales. If you have access to your support contract you will be able to work out your issues quickly.
Second, I suggest you hire someone at least temporarily to help you find out what you need to do and how to do it: Licensing, environment, scripting, test execution and analysis. Get a consultant. Good LoadRunner consultants aren't cheap and before actually hiring someone, talk to the consultant's previous customers. There are expensive consultants that are incredibly bad at their job as well, so price tag alone isn't a quality measurement.
Third, even if you install Vugen and Analysis standalone on your desktop, you already have a server (Controller, I assume) from which you will execute your tests. You do not need to install any licenses on the desktop on which you develop your scripts. The licenses apply to the Controller, not to Vugen or Analysis.
Again, talk to HP. They will be more than happy to help you out, but before agreeing to whatever licenses they suggest, check with a good experienced LoadRunner consultant.
