I don't think you can transfer calendar info that way. But it is possible to send and receive files over bluetooth to the storm, I have done it on many occasions with videos and pictures! And here is how (off the top of my head so names of options might be slightly different on the phone)...
The trick is to pair the devices, make your storm bluetooth visible and then go to the media player application. Hit the blackberry button and select "Recieve via bluetooth", then discover using the other device and send to the storm, accept the transfer in the prompt that appears on the storm and hey presto, file transfer begins.
I initially had problems getting any files to transfer to mine until I made it discoverable, even from devices that were paired and trusted so that part is quite key I think.
