first of all, don't while logged in user uid want change.
*
prerequisites
1 clean way of doing root user. that, have to*enable root user on mac os x. log in root described in apple's article.
*

not use sudo being loged in normal user if have admin privileges.*
*
change uid
read uid (given alice user's name, 501 old , 1234 new uid):

code:

# dscl . -read /users/alice uniqueid  uniqueid: 501     # dscl . -change /users/alice uniqueid 501 1234    # dscl . -read /users/alice uniqueid  uniqueid: 1234

*
change ownership of user's files

code:

# find /users/alice -user 501 -exec chown 1234 {} \;  # find /library -user 501 -exec chown 1234 {} \;  # find /applications -user 501 -exec chown 1234 {} \;  # find /usr -user 501 -exec chown 1234 {} \;  # find /private/var/ -user 501 exec chown 1234 {} \; 

or use 1 if sure no remote filesystem mounted

code:

# find -xl / -user 501 -exec chown 1234 {} \;  simple test if there files left owned old uid:  # find -xl / -user 501 -ls

rename special files , folders
not all. mac os x has special files , folders have (old) uid part of names. these include (on mac, ymmv):

/.trashes/501
/library/caches/com.apple.imagecaptureextension2.icadevicedatabase.501
/library/caches/com.apple.imagecapturenotifications.devicediscoverydatabase.501
/private/var/db/launchd.db/com.apple.launchd.peruser.501
, possibly files in /private/var/folders/ud/(some ugly dir name)/-caches-/
every of above have like:
# mv /.trashes/501 /.trashes/1234
