Love's Labour & the Lost Plays

I've been reading Love's Labour's Lost out of my roommate's book of the complete works of Shakespeare, and it had an editor's preface that gave some interesting information.  I thought we could gain some clues about our lost & found plays from some of the things that were mentioned about the play.  Let me just quote a paragraph from the preface* (see end of post for citation):

"The 1598 edition of Love's Labour's Lost is the first play text to carry Shakespeare's name on the title-page, which also refers to performance before the Queen 'this last Christmas'. The play is said to be 'Newly corrected and augmented', so perhaps an earlier edition has failed to survive. Even so, the text shows every sign of having been printed from Shakespeare's working papers, since it includes some passages in draft as well as in revised form."

...and later on, it says that while the names of the King's friends seem to have been taken from contemporary French leaders, the plot itself looks like it was invented by Shakespeare--so we can see that he didn't always copy existing stories.

Do we have any drafts of the plays we've recovered?  Is there reference to an event, such as performing before the queen, that would give us clues as to when the plays were written?  Do any of the plays include "foul paper" (prompts which actors used to produce the play, since printing didn't happen until after the plays were produced: see Plays and the Globe Theater)?

With other research (see here), I found that since there were no copyright laws in the Elizabethan era, some publishers would send people to sit in at plays and record them so they could essentially steal the profits--does it look like any of these plays had that happen, based on publisher information and date of publication? (Only 18 known plays were published like this during Shakespeare's lifetime.  I'll try to find out whether these unauthorized publications still listed Shakespeare as the author so that we have a better understanding.)

One last thing:  at the same site given in the above link, I learned that in Shakespeare's time, plays had to be registered before they were published since it allowed for censorship of too liberal political and religious views.  Maybe our plays escaped publication by the normal means due to questionable content that was too free-speaking against the crown or some social issue.
