I would consider using them exclusively for the flavor & aroma additions to a beer style you like, so you can get an idea of what their character is like: piney, citrusy, herbal, floral, etc.
If they haven't been dried yet, I would try them out for a few days.
Use a known pellet hop for your bittering addition so that you can control overall bitterness better.
If you use pumps to move your wort around, you may want to bag the hops or use a hop-spider, to keep them out of the pump intakes.
Good luck & have fun! Nice to have a good neighbor like that!
