So > is it really safe to assume that I don't need wear leveling??? For most Linux filesystems you really need wear leveling. E.g. ext3's superblock is at a fixed location and gets overwritten frequently. Without wear leveling you risk that the flash sector where the superblock resides wears out early. When using ext3 on a CompactFlash, you can limit the number of writes to the CompactFlash significantly by mounting the medium with parameters like noatime,nodiratime,commit=300.
