Yep. You asked it to. launchd launched it for you, and your app probably just sits waiting for something to happen vs immediately acting on args and exiting when done.
Delete them as Charles said. ;)

None at all, actually. Just supply the Label and (likely) the MachServices entry so that you can communicate via XPC or whatnot.

SMJobCopyDictionary(kSMDomainSystemLaunchd, …)
There will be a PID entry if it's running.

I just started doing this yesterday as well. Get the latest SMJobBless sample code and *read everything*. You have to understand all the codesigning nonsense before the sample will even run. It's actually not too difficult. I'm sorting through XPC right now making sure I'm doing it right, but it's all working.
