The easiest thing to do here is to add some of the info via a Registry key before the installation.  This is for the Client installation only.

=== Begin Mirror_Install.reg

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Mirror Image]

[HKEY_LOCAL_MACHINE\SOFTWARE\Mirror Image\Mirror Professional]

[HKEY_LOCAL_MACHINE\SOFTWARE\Mirror Image\Mirror Professional\Database]
"Default Startup Database"="servername-dbname"

[HKEY_LOCAL_MACHINE\SOFTWARE\Mirror Image\System]

[HKEY_LOCAL_MACHINE\SOFTWARE\Mirror Image\System\AuthServer]
"AuthServerCount"=dword:00000001
"AuthServerLHold"=dword:0000001e
"AuthServerMaxCount"=dword:0000000a
"AuthServerTWaiting"=dword:0000000f

[HKEY_LOCAL_MACHINE\SOFTWARE\Mirror Image\System\AuthServer\AuthServer00]
"AuthServerAddress"="servername"
"AuthServerInstallationID"=dword:00000000
"AuthServerName"="servername"
"AuthServerPort"=dword:00002382
"AuthServerSearchOrder"=dword:00000002
"AuthServerType"=dword:00000001

=== End Mirror_Install.reg
