I have this fly rod set up and I know nothing about it

[lucabrasi]

You need to make sure the line matches the rod. If it came as a package it probably does. If not you need to make sure you have 6 or 7 weight line. To learn on don't worry to much about cost right off the bat but flygoddess is right about cheap line. If you go get some line try and get weight forward line. It would say wf7f on the box. Weight forrward 7 weight floating line. You can get line for 20 bucks or so. That is at the low end for sure for line cost. Sounds funny you spend as much as the rod is worth but that is crucial to match up for the rod to work. I could take up a lot of space here telling you why weight forward is best to learn but just do a little search and you will see why it is best for a beginner. Lots of cheap combos come with level line. Yoy could learn with that but wf would be much better. Also if the line is old and cracked it won't slide through the guides well. Also it may be best to get 7 weight instead of 6 as it will make the rod work better for a beginner. Learn on this set up. You can for sure. When you can start casting without wind knots in your leader, snaping off your fly, and other issues pretty consistinently then look at a better set up. Lots of people, me included have learned on low end set ups.
Then you are hooked for sure, and all of the sudden there are countless fabulous setups to lure you in.
Also, if it lists a lure weight on the rod, well, that is new to me. Don't worry about it much to learn on. Just learn the motion and how to cast. Go after some of those planter rainbows. Also don't worry about long casts to start. Short ones 20-30 feet in front of you or less will catch fish for sure. Build up to the long casts.
