1. How and where is it appropriate to use an exclamation point?

You could Google these questions and get answers pretty quickly, once you sort through all the detritus that Google has no choice but to display. With enough scrolling and double-checking, you could, eventually, get all of these answers right.
Or you could use The AP Stylebook and Libel Manual.
You would not only get the correct answers a helluva lot quicker, you would also be assured that the answers are definitive. That's because the AP Stylebook is a constantly updated "work in progress," representing a couple of centuries of work by the worlds' finest journalists and editors.
Solutions to tricky punctuation situations, definitions of financial terminology, when to write 16 and when to write sixteen, and hundreds of other things you might have learned if you were paying attention in school are in this book. I use the thing every day because although I did pay attention now and then, I've forgotten most of it.
If you want to write well, get yourself a copy of this indispensable reference. Or get a subscription to the online edition. It's more valuable than a dictionary, thesaurus, or book of quotations.
Some prefer the Chicago Manual of Style and that's OK. Get one or the other and you will never have doubts about capitalization, ellipsis, time zones, or weather terms again.
You'll save yourself a lot of time, write more accurately, and save your editor – and your readers – a lot of grief. (Plus, with the AP Stylebook, you'll also learn how NOT to libel people.)
