comment rm intermittently causes disk to lock up
I would also ask to check if the process (or which processes) are in uninterruptible sleep (check for D status on ps's output), although if you say that there's 0% usage in wa, that's weird. But worth checking too.

comment Deleting very large file without webserver freezing
you are 'nicing' and 'ionicing' the deletion. Nice used to arguably prevent any CPU overusage, but the most important here is ionice, where you are actually telling the scheduler to delete the file with a lower priority. -c is for class, where 1 is real time, 2 normal, and 3 idle. Within class 2, you have from 0 to 7 (IRRC) where 7 is the lowest one. IF that still creates problems, run it with 'ionice -c3' and it should be fine.

comment MySQL replication Slave_IO_Running: No
I believe it's master_port=3307 on the line with the CHANGE MASTER TO. Also, make sure the my.cnf file is actually read by your MySQL (is it placed in the right place?). Check with netstat or lsof and see where it's running.
