Hi Robert. We use the same OSX build, and I've had kCGErrors for months, but they don't seem to affect LW (see Google for how it shows up with other applications).

The Java crash is probably more relevant--you can look at the limewire.crash.log from the Console file menu. Scroll to the bottom to see the last crash logged.

For ideas--shutdown the machine for 5 mins to let the RAM drain: this will make sure java is totally quit.

other ideas that might help: clean out the incomplete folder and restart the Mac. A safe boot/repair permissions can't hurt either. These are generic guesses though--since Apple fixed/ rereleased the QuickTime 6.4 and the java 1.4.1 updates, I haven't had any java crashes with LW 3.6.15.
