Nope. LMT's can help reduce the free space fragmentation at tablespace level. But row and block level fragmentation will need reorgs. So, proper configuration of db block size, pctfree and pctused becomes important to minimize such fragmentation. Even if you had set decent storage initially, it can and will get mucked up based on what processes do and how, to the objects within the tablespace.
So, hang on to whatever scripts you have for reorgs. Not sure what 9i does, though.
