If so, and I > have a threaded application, what signals are still available for use? No, the threads library that comes with 3.x/4.x does not use SIGUSR1 or SIGUSR2 for anything. It does use SIGPROF via setitimer for its internal scheduling mechanism, and SIGINFO to dump thread information (to aid debugging), but the other signals are available. Perhaps you're confusing libc_r with LinuxThreads which also runs under FreeBSD. I believe LinuxThreads uses SIGUSR1 and/or SIGUSR2.
