I also grow my own hops. I got my rhizomes from freshops.com. Their site has lots of info on hops, including how to properly dry them. I believe they need to be dried, regardless. I used a large window screen, propped it up, and set up a small fan to keep air circulating around them. I fluffed them a couple times a day, and when they were to the proper dryness, I just weighed them out, and vacuumed them with my foodsaver, and put them in the freezer. I just brewed a batch of ale, and used some of them in it. They seemed to be just fine. I also put in three more varieties, last year. I am hoping to have a decent harvest from all of them this year.
