2) The main thing you need to find out is what Chase will charge you for the balance transfer. Most banks charge between 3 and 4% of the transfer balance as a fee. Also, read the fine print in the terms of service agreement. Many of these 0% transfer deals have a clause whereby if you are late or miss a payment, you could be charged interest on the entire balance back to the day you transfered the money to the card...and the interest rate is generally the typical high credit card rates (12%+).
Yes, this is exactly what I was going to say. Whereas I used to see some 0% APR balance transfer offers without the initial fee, nowadays the only ones I ever see have the 3 to 4% fee up front. Also, that's correct that any missteps in repayment on such 0% introductory APR offers can have major interest consequences.
