I couldn't resist again, but if "today" means Oracle 10g you can use "alter table shrink space cascade" (after you've allowed row movement on the table) which will compact both your table and it's indexes online and even lowers these segments HWM.

It doesn't lower index'es height though, this would get too complex to handle..
