Urahara is shown offering the Gigai to Rukia sitting in the street with her white robes on. This was obviously after she gave her shinigami powers to Ichigo. She didn't need a gigai when she came to earth
Rukia did not disappear after Ichigo got his powers, she sat there and watched him kick the hollow's ass. Then the episode ended. I suppose she got the gigai in the time between episodes 1 and 2.
