I use titanium backup. You want to backup everything before you start deleting because you might want those suckers back one day (maybe never, but just in case). All you have to do is go to the batch operation and then you should see the section to delete the apps. Go through the list and make sure you check on the ones that you want to delete. Be careful with what you are checking on the list.
Another way to do it is to freeze the app. This won't delete the bloats all together, but it will freeze in its place and won't use any of the device's resources.
