Your settings look like the stock settings for a MM or MMM except for the 10% drag break. That's as good as any place to start. If I was to change anything I'd set the Lipo cutoff to custom. I'd set it at 3.2 - 3.4 volts per cell. I also prefer the forward with brake lock-out. That means the esc has to sit for a second or two in neutral before it goes to reverse. With the fwd/brake/rev setting it goes into reverse as soon as the vehicle stops.

As far as Castle software their web site is rather confussing. The software that is labled Pheonix also has the updates all the Castle ESCs. So download that one and it will update your MM or MMM.
