yes your right with the 2 pipes on the bottom - right asshole but patience you will pervail. You will need a new gasket to put the plenum chamber back on if you take off, also worth changing the PCV valves whilst off if they haven;t been done recently.
The other connectors you are right they are the injectors.
When you do the 6 bolts up in the middle make sure you dont over tighten them as i did and break the part underneath as it is only aluminium - never has been the same, got a new one but will get round to fitting it one day.
