about 1. I don’t know any special software but the clips in fcp are searchable once they are logged. you can search the metadata you entered in the log and capture window or the browser window (the browser window looks a bit like an xls, doesn’t it?)
…or you can export a batch list and import it with excel to create an xls (I have done this for docummentaries).
i can’t help you with number 2 at the moment.
