To do either part of your question you need to be a paying member of Project-GC, which allows you to create a custom filter. (click your name in the top right corner of the screen, then custom filters).
Once you have a custom filter specifying a cache owner, you can use this with nearly every map tool that Progect-GC has, showing the data on a map, or as a list under the map, which then can be exported if desired. Map compare is often the best map to use, note that you can just enter one name, no need to compare with anyone else.
Create two custom filters, one with you as the cache owner, so you can see if people have found your caches, and another with their name, so you can see if you (or anyone else) has found their caches.
