Pretty sure it doesn't work like that. The possessions he had with him when he died become incorporeal, but anything else you can't interact with except by telekinesis unless you have the Ghostly Grasp feat from Libris Mortis.
i was not talking about the ghostly equipment ability...
it is the incorporeal subtype that does that...
monster manual III page 214:
Incorporeal subtype:
any equipment worn or carried by an incorporeal creature is also incorporeal as long as it remains in the creatures posseion.
normally you cant touch anything when youre incorporeal
but ghostly grasp allows you to pick up stuff and then it becomes incorporeal since it is now worn/equipted by you...
the moment you let go it would become corporeal again
