How about a PC or Mac and some software to edit it all together on?
Also, I'm curious. What are the extension leads for?
Other comments....
Camcorder light. What's this for? Are you looking for the camera in the face type of interview. these lights (if youhave what I think you have) are not able to light a room so you may want to think abotu getting some 'real' lighting. The purists will disagree no doubt but if budget is at a premium then it;s amazing what can be achieved with a couple of £5 floodlights from B&Q. If you have a green screen then you've probably noticed by now that it needs lighting properly.
Also, there's plenty to say about microphones. With an FX1 having a seperate microphone is pretty much a must once you realise the inbuilt one is really there just for decoration

But what you get out of it will depend on what it is and how it is mounted.
Also, for filming with an FX1 I found getting one of those hoodman things a godsend for filming outside.
And, as I have the same camera, I'd be interested in learning what wide angle adaptor you have, where yougot it, howmuch it was and is it any good. PM mewith details if possible.
Other good gadgets that I find useful. A big 5-in-one reflector and some kind of steadying device.
