ECC 6.0 Client Copy - Source Cl User Master?

Question

When completing a client copy I have created the new client using SALE - Logical Systems - Define Logical System
I created a test client 900 (which I would like to build from our golden client 200) I have a couple of questions.  From the documentation I am using it indicates that after completing the definition of the new client.  we should reset SAP* by adding login/no_automatic_user_sapstar = 0 (which I am familiar with)
rebooted SAP (previously backing up the kernel of course)
Log into new client 900 and create a user to later use for RFC destination configuration.  Unfortunately this new client may not yet contain any data so that when I try to create this userid none of the drop downs in SU01 contain data.  I was able to create the new user BUT it has no profiles etc... that I can assign.
This is my first question... I think this user should be configured after the client copy??? right?
Last question,
When I run SCCL I want to copy from client 200 to NEWLY created client 900.
So the entry screen should go something like this (please confirm)
Target Client       900
Selected Profile   sap_all
Description          All client specific data w/o change options
Source Client                      200
Source Client User Masters  200
my question also, do I get User Masters from client 200 because there have been HCM table configurations etc... recently applied or do I get this information from client 000, My guess is I would get it from client 200.
sorry for the long message I just wanted to provide background.

Something else occured to me...
by creating two additional clients in my QAS server and only one instance of SAP is installed ... currently only two clients exist 200 and 600 and they EXIST in all three environments dev, qas and prdn.
BY introducting two clients ONLY in QAS how will I transport items from client 200 DEV to 201 or 202 QAS? Will I need to make changes to stms? if so what?
The purpose of adding these additional clients is to separate testing, training  and parallel testing that our PeopleSOft migration project team (migragation of Peoples soft to SAP) for HCM will nedd to .
