Robert, The wide variety of panics you're seeing (some instruction miss, some data) make me believe there is memory corruption of some type going on, which makes me suspect the RAM in your TiBook may be acting up (or is overheating.) Specifically the last trap you received - the Unexpected user state trap of 0x401 - should never occur. A reinstall of 10.2.2 couldn't hurt but you may want to run your Hardware Test CD first just to see if it has any RAM complaints...
