Sounds like you did your research and purchased the right items assuming that 4000 watt inverter has it's own internal transfer switch there is no need for another transfer switch for the inverter, but it sounds like you have a need for a more knowledgeable installer. What you now need is a sub-panel that has breakers for all the loads you want powered by the inverter. Move the breakers and wiring for those loads from the main panel to the sub-panel.
The output of the inverter will power the sub-panel. There will be a feed (from new breakers) from the main panel to the AC input on the inverter. That will get you to what you are trying to do.
