Not sure if you've seen, but I've posted elsewhere that the OS is smart enough to toss out unneeded stuff in the "other" section when it gets low on space. I've tested this multiple times by overloading my phone with more music than it can handle. I've had it clear over 1 GB of stuff from that section using that method, so you shouldn't have much of an issue.
