The following link is to an online file converter. You can upload any sound file and convert it to ogg, wav, mp3 and wma. I use this site all the time. You can use this to convert sound clips into files for your PowerOff and PowerOn. Once you download the converted file, name it PowerOn.ogg and replace the file in SYSTEM/MEDIA/AUDIO/UI and when you boot the phone on this is the file that will be played. If you want to do PowerOff sound file make sure to make an OGG and a WAV file the Off sequence.
Make sure to make a copy of the original PowerOn or PowerOff file, in case you dont like what ever you made.
