Welcome to the fun. You will probably find as I did that as you read, learn, research equipment within your budget and buy and put that stuff into use, that you will probably never be completely satisfied. Not trying to discourage you, just stating fact as I see it when someone gets bit by the precision shooting bug.
This is a challenge that we impose on ourselves and the journey is a lot of fun. There is an almost limitless variety of equipment types (for different shooting disciplines) and levels of quality and precision (yes, you usually get what you pay for) that you will never be able to stand back and say "yep, I've mastered this...time to find a REAL challenge". I predict that you will have a pile of stuff in a few years that you had purchased, tried and then researched a little more and bought your way up to the next level. I have that pile!
I have learned more from the folks in this forum and also the 6mmbr forum in the past few years than I thought possible. Another resource in your shooting education will be found at shooting competitions. Notice I didn't suggest any specific form of competition. Find what shoots take place in your area, especially the shoots that allow you to use your gun. Go, make friends, do some shooting and keep your eyes and ears open.
You have been given lots of good advice in this thread. My 2 cents are as follows. Get a scope on the gun. Do some shooting with it and get comfortable with your gun. Try to get out to 300 yards or so and have some fun with that. Go to local shoots and SHOOT YOUR GUN with those guys. Look at their equipment (you won't be able to take your eyes off of their stuff!)
You seem like a smart person. You'll figure it out for you.
Have fun!
