In addition to the good information by Glen, I find that Transparent mode gives you more control over where you extend your broadcast domains. In such sitations you are specifically required to configure the vlan on switches.

Therefore transparent mode is better suited to static enviroments where you are not constantly moving ports between vlans across access switches.

In your case, it is not necessary to configure the switch as a client in order to learn additional vlans.

Once the switch has learned all the VLANs through VTP and then you subsequently change the mode back to transparent, any additional vlans can be added manually to the switch(s)

It is alway good practice to ensure that VLANs are cleared of trunks where the are not necessary. If certain VLANs are not necessary at the edge, then VTP pruning should be enabled.

It is generally recommended that you should have two VTP server within the domain, specifically for redundancy purposes.

Previously most switches default to VTP server, therefore it is always prudent to ensure that you check VTP mode and revision before adding it to the network.

However, if your network remains constant and hosts are generally assigned geographically then there is little advantage in using or configuring switches as VTP clients.

I would not expect new VLANs to be added to the core device and then trunked to all access-switches. Otherwise broadcasts will be flooded across all trunks which have that VLAN memeber where the broadcast originated.
