What a hyphen does is it is showing you what you are saying in the sentence; it represents something. It is NOT to be used as a pause. Commas and semicolon's are used for that. For example, if I wanted to say something about a car, I would say "This car is very nice - it has leather seats." The hyphen is a place holder if you do not want to end a sentence because you are describing what you are talking about in the first part of the sentence.
"The well-known actor starred in the award-winning film."
No, the sentence should use a hyphen to connect "dead end" as a compound modifier: "He knew he had a dead-end job the first day he showed up for work."
"Steve and I are going" is correct. Use "I" as the subject of a sentence and "me" as the object. In this case, "I" is the subject performing the action of going, so it is the appropriate pronoun to use.
No, the sentence is not correct. It should be: "You can wear whatever you want." "Where" denotes a location, while "wear" is the correct term for putting on clothing.

Yes it's correct.
Since you're changing it into a superlative, you're definitely going to use two separate words, so no hyphen is necessary.
Email is correct. Some people still use e-mail, with a hyphen, but email without a hyphen is used much more often.
Yes. "Hard-working" is a compound adjective, and therefore requires a hyphen between the two words. It is also correct to omit the hyphen and use the single word, "hardworking."
It depends how you use it. If you use it after something it can be correct. But being in a sentence by itself isn't correct.
Use is present. Used is past. The correct sentence is, This is used for....
If you use 'you and he' as the subject of the sentence, it is correct: You and he will meet when we get to the restaurant.
A dash is used to connect two phrases; a hyphen is used to connect two words. Here are some examples. I use a hyphen for the compound word anti-matter. I use a dash to create a break in the flow of my sentence -- if you know what I mean.
No, a capital letter is not used after a hyphen unless it falls at the beginning of a sentence or is part of a proper noun. The word after the hyphen should be lowercase unless it is a proper noun.
