You can leave the manifold on - just makes it heavier. I leave the wastegate and corrugated pipe on as well. Just undo the 3 nuts from below for the downpipe

I'd suggest taking the turbo off though because there isn't really room to lift it up and out with the turbo still attached.

Is the timing belt fairly new ? You can leave it on the bottom pulley and just rotate the water pump to release the tension. The danger is getting the fluids onto the belt which is why I usually replace it.

You'll need to remove the cam pulley to get the rear timing belt cover for lifting the head so make sure you're at tdc
