It's nice to have all the toys, even if you only use most of them on extremely rare occasions. However, you don't HAVE to have any of them to learn how to shoot. Focus on getting good quality basics: rifle, scope, and LOTS of decent ammo. I would add to that list a shooting mat, bipod (preferably) or front rest of some sort, and bean bag for the rear. You really don't need much more than that to get started. What's more, regardless of the recommendations you get here or elsewhere, if you go out and buy a ton of stuff right now, you're almost certainly going to find out later that some (if not a lot) of what you bought isn't exactly what you really need or want when you actually get around to using it. Why waste money like that? Get what you need to get started, and get the best you can reasonably afford. As time goes on, you'll have a much better idea of what to buy next.
FWIW - I personally found having a chrono extremely useful right from the get-go. Having tried a few different types, I now use a MagnetoSpeed:

I view the MagnetoSpeed as some of the best money I have ever spent on shooting gear. Anyhow, good luck with the journey, it can be frustrating at times, but it's an awful lot of fun, so remember to enjoy yourself as you go through it. That's what keeps you coming back.
