It's a Japaneese joke. Ukitake's full name is Joshiro Ukitake and Toshiro's full name it Toshiro Hitsuguya. Joshiro and Toshiro sound similar and the names have similar charectors. Also, they both have white hair. Ukitake finds this is perfect reason to give Toshiro gifts, for some reason. It's funny because he always ends up giving it to Yachiru, the vice-captain of squad 11.

No. Sadly, he doesn't. But you can look on-line for stories about him getting sick. It would be nice to see everyone's reaction to him getting sick! XD He sneezes in one of the DS games, but that's just because Ichigo and Ukitake are talking about him.
