the admin users

Hi Guys 

Can someone please point me in the right direction as to how i can hide the admin users , i see that are listed as admins in the database so where can i stop them showing up in the search and lists. Im also not sure about composer and elgg , I tried to get the papal api up and running  , i can see there is a bunch of stuff in it and it activates ok, but how do you use it , where are the manuals for the plugins .

I would appreciate any help you guys can give me
