You will not find a plugin for a relatively small number of functions like this; I think this snippet should just cover it:
$("object").append( $("<param/>").attr({ 'name': 'wmode', 'value': 'transparent' }) ).find("embed").attr('wmode', 'transparent')
I am not sure when it is better to launch it; ready might work, but I expect it might be too late since Flash content has already been embedded? Worth experimenting with.
