Hi, I got a PM from Herr Professor, but I thought it would be better to answer it here, in case some more people have questions.
I took a look at the thread and you have a nice bunch of options there.
I have no Famo, neither I have seen one in person, but first of all you have to check what is the available room inside of it, to check if the electronics fit inside of the model or not.
What I would do is for sure different of what I recommend you to do, because you want a KISS solution. But doing a fast overview the options you have, and considering everything fits, you have:
IBU 2 BASE: Oh, memories... That was my second hobby grade board, it should provide you all the control and options you need, but you will need to plug a servo to a spare channel in the radio for having servo steering. I have seen it comes with the audio amplifyer attached, you can remove it, the sound the board provides is in my opinion more than adequate. I believe this option would be the easiest for you.
Old Elmod. Pretty much like the IBU and the need of servo in the spare channel. But keep in mind there will be a inertia/momentum that you cannot remove. Some people absolutely love it (For example Herr Jimster) some people hate it, and some are in between like me. So it is your choice.
Clark board: I would stay away from it, I don't like clark products and triggering the functions means very advanced radio programming which you cannot do with your current radio equipment or playing mortal kombat-street fighter 2 with the control sticks.
Benedini board: That would be my personal choice, but you need a double speed controller (about 10-15 eur) The Benedini will provide you all the sounds and lights needed. But at the other hand those boards are very complicated to satisfactorily use (hence is the only one electronic I had to write tutorials in my website!) and you will pretty much need a better radio, which I always say is the most important part of the hobby and is a must, and you only need one.

Small example of what the benedini board does can be seen here,

Hope it throws you some light.
The kit came with some instructions titled "Servo Multi - Function Control Unit." The instructions do show a multi-function board, but it was not included and I cannot now find it on the Asiatam web site. From what I can surmise, the board shown in the photo here is actually to be linked to the (mysterious) "multi-function control unit."
