Okay, I got ahold of them, and they told me my limit! It's 1500. That means about half my requested transfer will likely go through. (Original request, $2900. Assuming that the full 1500 goes, that would be 1500 on the 0% APR card, and around $1400 on the 19.24% card.
Mathematically speaking, what would be best:
1) Paying the minimum on the high interest card, and paying down the 0% APR first, then transferring the remaining balance on the high interest card over.
2) Paying the minimum on the 0% APR card, and paying down the high interest card, then snowball that over to the 0% APR card.
