Periods and commas are always placed inside the quotation marks. Colons and semicolons go outside the quotation marks. Question marks and exclamation points go in or out, depending on whether thy belong to the material inside the quote or not. Logically, if they belong to the quoted material, they go inside the quote marks, and vice versa. If you are wishing to emphasize a word or two and it's not a book title, you can also use bold type, larger type, or a different font.
All caps are much harder to read.
We recognize words not only by their letter groups, but by their shapes. When words are in all caps, you can't tell their shapes apart. Never use the space bar to align text. If you want things to align, you must use tabs. Avoid more than two hyphenations in a row.
