Preventative Maintenance During 30K Service

My 1997 F355 Spider will be going to visit Rifledriver for its 30K service in a week. In addition to the standard 30K items (including water pump), what things would be good to consider changing, or having done, as preventative maintenance items? I am already considering swapping my headers for reconditioned ones from QV. I have also installed the Helms gold connector kit. My clutch was redone over the winter. My alternator has been rebuilt and the tensioner bearing replaced already.
