Question: The US emergency telephone number 911 seems to be almost always pronounced as nine one one whereas the Porsche model is typically pronounced as nine eleven One reason I can think of for preferring "nine one one" for the phone number is that there is no "eleven" key on a phone. On the other hand, "0800" is often pronounced "o eight hundred". Is there a logical or historical reason for the different pronunciations? 
Answer: How a car manufacturer names its models is more of a marketing preference than anything, but in general you'll find that the Porche model is the norm. Ask any schoolchild to read aloud the number "911" and you'll get "nine hundred and eleven", not "nine one one". The telephone number 9-1-1 was, as you speculated, spelled out specifically to prevent people - particularly children - from getting confused looking for the "eleven" key on the telephone. I have heard this anecdotally countless times, but I'm having a hard time finding an authoritative source. Closest I can come are various "history of 911" websites like this one: Dr. Phil Shaenman, head of the U.S. Fire Administration's research department, authored a paper explaining that children should be taught to dial "nine-one-one," and not "nine-eleven." He pointed out that a child's conceptual abilities prevent them from recognizing the difference between "11" and "1-1.".
yes

Question: In Russian we have the term "". I would translate it as "asshands" which literally means that your hands grow out of your behind and you can't do anything right (or do anything at all). Example: Dad: "Hey son, can you hang up this picture on the wall?" Son: "No dad, my hands grow out of my behind, I'll probably end up hanging it upside down" (Or "I am a _____" - i.e. the term I'm looking for.) Is there anything similar in English? Is the term "screw up" the one? Or are there any other ones? I want slang specifically, preferably American. 
Answer: There is a word we use called Nixie. It comes from the German word Nichtse which means a slacker/good-for-nothing. The word is very popular among the Pennsylvania Dutch community.

Question: If you, for example, have to add a person to an application whilst that person is on the phone, how do you politely ask for that person's gender if the voice and/or name has not proven decisive? To clarify why I posted this question on this site: I was looking for an answer within the context of the English language and usage. The given answers have proven that this question really isn't off-topic, other languages know different distinctions that are relevant to addressing this issue. 
Answer: I totally agree that this is not really about English language usage but here's a suggestion anyway...preface the question with an apology, "I'm sorry, but I'm required to ask this question, even if it seems obvious, may I have your gender please?".

yes
