Well, welcome to the forum to begin with.
You can add a cold air intake and freer flowing exhaust to start.
Programming is available but it's an expensive proposition right now, consisting of a programmer and a second PCM that is modified by DiabloSport. Once folks figure out how to get past the program encryption placed on the PCM by Ram more, and less expensive, options will result.
3.21:1 gears aren't optimum for performance but they are great for mileage. I assume you have the 8-speed transmission? You can do a gear swap to improve torque + off the line performance.
That's about it as far as programming and bolt ons at this point.
Good luck!
