5.7 uprgrades

I just recently picked up a 97 1500 with 51k miles on it. I had a 5.3 and did some performance upgrades to that, but the 5.7 is a new world to me. Where do i start, what should i do? It has dual exhaust nothing special, also wondering how to get rid of the moderate cackle if even possible. I wont be doing anything serious, like boost. My 5.3 was a 03 Tahoe that was lifted with 35s and had long tube headers and dyno tuned. I know that will be a stretch to get a 5.7 to that point, but what are my options?

To do any real tuning you'll need a 0411 pcm.
