Since it runs, I would not jump on making any changes right away.
Here's why.
I tell you to go put a Performer RPM on and your mechanic buys a Performer at retail price, charges his add on, and then his time to install it. Now you've spent a bunch of money and its not even the intake that some guy on the internet recommended.
My point is you need to get yourself up to speed enough you can begin to understand what the different parts do, what the parts do, a brand, the part names. I don't know how much better it will be going to a car show. There are plenty of a people at car shows who talk like, and maybe think that they know alot about engines and performance but are essentially just BSing. How will you be able to seperate the fish stories? If you want performance, look to see who takes their cars to the drag strip, or works on roundy rounders, or other competition. You'll have a better chance.
