On copyright
First, since no one has pointed it out, it is copyright, not copywrite.
While editions of Shakespeare are technically under copyright, your chance of having a problem just by quoting even an extensive passage is nil.
In general, the various editions of Shakespeare are built on one another. Editors use the emendations (changes, corrections) of other editors. There is a whole tradition of editing that goes back for centuries, and there are debates about whether a line should be corrected this way or that way. Many of the early printings, whether the First Folio or the the various Quartos, contained mistakes about which character was speaking. Spellings have been modernized. Sometimes guesswork is involved in what to do about a confusing line.
You do not have to limit yourself to the Folio or to nineteenth-century editions when you quote. In fact, you would be doing yourself and Shakespeare a disservice to try to use those original sources, which are full of errors that editors have puzzled over and corrected (maybe) through the centuries.
If I were you, I would look at two or three modern editions for my extended quotes. See if there are any significant differences. I do not think that you will find many differences. If so, you can decide which versions you want to use. But you are not prohibited from using modern spelling just because somebody put out a copyrighted edition of Shakespeare.
