To use srvany (not that you need to now) just put it somewhere (%systemroot%) and install the service with the above command (instsrv %whatever% %systemroot%\srvany.exe). To start it type sc start %whatever% at the command prompt. This only starts SrvAny - you need to manually add the progs. Obviously you also need instsrv.exe for this.

There is an excellent step by step (including adding programs) here http://www.haxial.com/faq/auto-startup/mswinservice/ which also includes links to some other 3rd party apps. Your app looks nice though be sure to post back if it is all working lovely, some apps will shut down when you log off even if you started them as a service so check that out too.
