X100 black new owner - some questions.. please answer

Hi I am going to buy a new Fuji x100 black limited edition on Friday. I was reading a lots of threads but I still have some questions. If you can, please answer me.

1. I found that x100 has some problems with dust in viewfinder. I wanted to ask you if its a common problem. I dont care about a few dust particles but what if dust covers all the OVF. Is it possible to clean it by myself? Becase I dont think Fuji will remove or clean particles under warranty - all cams has dust problem but dust in OVF without any possibility to clean is bad.

2. Is there also any problem with dust in lens?

3. I can live with SAB threat but I hope Fuji solved that problem with that newer models (like black and silver 2012 models).

4. I was reading manual of X100- theres written you cant use 1/4000 at f2. So if I understand that well you can use ND wilter (or adjust ND on RAW button) and use it quickly if its possible with time like 1/1000? I want to use f2 most of the time so its important for me.

5. Focus with new firmware is ok?

6. What about camera lugs - I found thats another common "problem" . Camera lugs takes some damage with the time? is that true?

7. Is there any other small problem which I should care about?

8. Do you know which serial numbers are these black limited versions?

I used to own 5D mark II (still have A second body), Sony NEX 5, 5N and NEX 7. I am looking for all around camera which has great IQ with some minor limits.. I am also looking for "joy to use cam" . 5d mark II ist joy to use but has great IQ. NEX cams looks like small compiuters and I dont have a fell they are cameras. And they also hve pretty bad jpg..

Thank you for your answer.
