What follow isn’t legal advice. I’m not your lawyer, you’re not my client, and if you believe anything I say, it’s at your own peril and you’re a moron.
Typically, you don’t file discovery requests or responses with the court. Courts get a lot of paper, and they dislike getting things that don’t involve them. Discovery typically is dealt with between the parties, and if the court has to get involved, then someone typically files a motion asking the court to do something (and would attach the discovery at issue to that motion).
As for a verification, the form will likely depend on the rules in the jurisdiction in which the case is filed (i.e., federal court? state court? which state?). Typically, a verification says that you have read the interrogatories and their answers, and you know the answers to be true based on your own personal knowledge, and that on that basis you verify that the answers are true. You then sign the verification under penalty of perjury.
The exact language is, to some extent, important. In California, for example, if you sign “under penalty of perjury” without identifying the location where you signed (i.e., “Subscribed this fifth day of December, 2008, at Los Angeles, California”), the verification is inadequate. If, on the other hand, you sign “under penalty of perjury under the laws of the State of California,” you don’t need to put your location.
In Hawaii, also for example, in addition to verifying the discovery responses, you need to have your verification notarized. California has no such requirement.
I recognize that this doesn’t answer your question, but instead simply provides generalized legal information. To find a particular answer, many jurisidictions have form books or practice guides. In a form book (i.e., Matthew Bender’s California Forms of Pleading and Practice) there are examples of just about every kind of pleading you could want to see. And California also has Rutter Guides to Civil Procedure; the grey one is for state court and the red one is for federal court. You may want to take a look at a local law library to see if there’s something there to help you.
