I initialize the hard drive on my iBook about twice a year. I just love that "zippy" new computer feel after a good scrubbing.
Reformatting a running drive shouldn't be necessary and is not advised. Reformatting involves blowing away the soft bad-block map (the hard, aka manufacturer's, map is retained). That leaves you with a file system that will potentially use marginal blocks for your data.
The performance improvement, with the classic Mac OS, comes from the out-and-back defrag. Backup, initialize the drive, reload it - the files are put on contiguously. Unnecessary under OS X, as the same performance improvement there comes from running simple maintenance tasks. OS X does the important defragging automatically.
