Tune it up well, find a mentor & leave it as it is for now. You need to learn technique before you need all the mods. Learn the tree, get consistent with what you have (THAT'S what wins races) and the other stuff will fall into place. For a stock, 318 car on a 1/8track slicks, NOS, etc. are all "luxuries" ---- just enjoy the car & the new experience. Learn track procedure, etc. & you'll do just fine.......
