Yes, they do.  Most of these tools are wrapped with cedet-* functions to 
make getting that sort of thing easier.  For example, after (require 
'cedet-global) you can do M-x cedet-gnu-global-show-root

There is only ede-find-file, which could certainly do with a completion 
helper.  To be honest, I remember very little about it, but I suspect a 
new completion method would be needed for each locate implementation 
(one each for global, idutils, etc).  The support in cedet-* for each 
would need to be added for that particular feature as I only added 
tagcompletion support.
