Definitively i like your concept of putting this "block with image and buttons" in the top instead of the middle 
and its not hard to change this content...
btw the website needs much better screenshots! lol, sometimes i try to use one and realize that there's not
The slider thing is a little controversial thing, it is good and bad at the same time lol, maybe it should be put in a different place...
the hardest thing making a website is the difficulty to see it with the same eyes / view as the new people that enters on it, without their already-known information and without know their "novelty feelings" and reactions
BTW @triantares did you see the results of the poll? 
User's feedbacks from the website it was interesting, we can create more polls too 
but i dont think we need too much at the moment
