For ur first question, how was your score for each part?

Ur second question, it depends on how many school you want to apply and how many hours you will spend every day.

The third question, usually second round deadline is in January. There is almost no difference between R1 and R2. However, for international applicant, most schools require you to send your application before Jan 15.

First, your listening score 59 is relatively lower than several top-20 schools' requirement. That means you're not qualified to apply those schools.

Second, If you can spend 5-6 hours a day, you might be able to nail down at most 3 top schools.

Based on all those information, uncertainty about your GMAT + strong suggest you re-take TOEFL + lack of time for essay, if you still aim at top-20 schools, I would suggest you to apply for 2007. That way you may have much better chances.
