if you have the S+ stuff you don't need the egg and poop collector, since thats in S+, ID recommend looking up auction house V3.1.2, auction house addon dino preview, upgrade station, classic flyers, meat spoiler and lethals reusables, Dino storage V2 is also nice. also if ur allowing element (not sure if crystal isles has element except for the dust from tek dino's and the Bossfights) a element transfer mod would be nice.
I'll post the links of what we got on ours, might be easy to look trough.
