you have way too many sound sources in this size case - you do not have the modules that you need to support half the sound sources you have
is the case a intellijel 7u? if so why the uZeus? will the uZeus even with the big power supply be enough for the modules if not (remember to leave at least 25% headroom)
some of the modules do have built in vcas - but that does't mean that you won't want more - vcas are also useful for controlling modulation - you may also find that you need some envelope generators to open the vcas - usually sequencers output gates - which are just on off square waves
I would try to start of with a single voice - sound source, sound modifier, modulation source, a way to play and a way to listen and build from there - you will quickly find there are things you are missing that are near essential - something like a disting is a good idea to buy early on as it has a lot of functionality and will help you understand what different types of modules do

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
