At the very first Artifical Chaos robot, jump off the pole and jump-dash into it for 500 points. You can also roll into a shielded robot by jumping off another pole short of it ending, for 500 points. When you fly out into space using the Light Dash, keep running to the Chaos robot that spawns the blob things, jump on the head for another 500 points. Figuring out Action Links is the way to go. The gold beatle is located in the long hallway to an anti-gravity transport deal, jump off the pull about midway and run to the left, it'll appear in front of the 2 sheilded robots.
