You're in a good place with a good starting point. The rifle you have is a great base from which to start. My recommendation for you would be to read, read, read. Then read some more. After you're done reading, take what you've learned to the range and shoot, shoot, shoot.
From your reading you will eventually learn the definition of all the terms.
From your shooting you will learn everything about your gun and cartridge. From that you will begin to have opinions of what you want or don't want, what you like and don't like.
From all this, you will be able to ask more precise questions and get more precise answers.
So that's my general answer. For something more specific for you, I have several recommendations for your current rifle.
1. Get your barrel free floated. If you're a little bit handy, this is something you can do yourself (wouldn't take much to find instructions on this site or someplace on the internet). By free-floating your barrel you ensure that nothing is touching your barrel which can influence how it behaves when being shot and it's more likely it will behave the same from shot to shot (remember, consistency leads to accuracy)
2. Have a gunsmith work on your trigger and have it set for 2.5 or 3 pounds of trigger pull. By reducing the trigger pull, you reduce the amount of tension (or influence) you have on the gun during the shot.
3. While the gunsmith is working on your trigger, have him check your scope bases and rings - to ensure they're rock-solid in place. You would be surprised how many people think their rifle is terribly inaccurate and it's really just a loose scope ring or base.
Hope that helps.
I'm not gonna shoot here. I'm gonna shoot waaaaaaaay over there!
