Welcome and congratulations on what sounds like a great first rifle. If you have an outdoor range/club nearby, I would go there, meet some folks, plan on attending at least one class or event, and hopefully find someone who will mentor you along the way. It is often difficult to navigate the information/misinformation available on the internet but this site is a good place to start.
I will say this though, if rimfire rifle is your passion, may I suggest heading over to Rimfirecentral where you will find a mind-blowing wealth of information, opinions, experience, and advice for just about every rimfire discipline out there.
