Question about quotations?

[Mnkys njoy nanas!]

Okay, so I'm writing this thing for fun, and this has started to bug me. Just a few questions.
a) If I'm saying something like: This is a "world."
Would I use the two quotation thing, or the apostrophe (This is a 'world.')? I've seen both.
b) In the above sentence, would the period go in front of or behind the quotation?
c) When doing dialouge, I know you must begin a new line for each person talking. Do you have to put an indentation there?
d) For the heck of it, what is the latest thing you've read or written?

A.S Byatts Possession is the last thing I have read....amazing!

When quoting a word in a sentence, like:

Beatrice and Benedick have a 'merry war' between eachother throughout Act 1. You use the single quotation marks.

Ignore the person above - this is the official UK way of doing it!
When quoting in a separate chunk or a sentence in a a paragraphy you use the double quotation marks:

For example: "Alas por Yorik I knew him well."

or a large amount of writing with a quote indented:

".....sd.sf.s.dg.gs.."

[fluke]

the one mark (') is used only for a quote within a quote.
In the US, period or comma comes before last quote mark. In the UK, after.
Indent not needed.

a. Use the quotation marks on a quotation used originally. Use the single quotation mark for a quote within a quote.
b. generally, the period goes before the quotation mark.
c. Yes.
d. Tin Roof Blowdown, James Lee Burke.

[Jub Jub]

a. Quotes, not apostrophes.

c. Punctuation inside the quotes.

c. These days, people put a line space between paragraphs instead of indentation. But each new person talking typically starts a new paragraph.

d. Read? Reading "Another Roadside Attraction." Written? A training video script.

[ritzycrackers]

a) I would say the quotation marks.
b) Behind, of course!
c) Yes, you do,
d) Sun and Moon, Ice and Snow by Jessica Day George. A kind of Beauty and the Beast, fairytale, folktale, foreign infusion. IT'S REALLY GOOD.
