Questions from a Tube Preamp newbie

I have my Rogue RP-5 back from warranty repair and I am loving how it sounds. While at Rogue, they installed 4new JJ 12au7-s tubes. Sounds great. I have some questions.

1. with about 2 hours daily playing, how long do typical preamp tubes last (I have heard Rogue's, like CJ, can be hard on tubes)

2. Do new tubes need broken in? if so, what is normal time frame?

3. Does tube rolling really make a difference on a preamp vs power amp?

4. What is the general concensus on JJ tubes for a preamp? Again, I am really happy with the sound, so I probably won't change. However, I will eventually probably get the itch.

Thanks

Picked up a pair of Telefunken 12au7's and a single 12ax7 from Andy Bouwman at Vintage Tube Services this past summer for my integrated amp. (not a Rouge)  Andy is extremely knowledgeable and fair in his pricing. He is a straight shooter and won't just sell you something for the sake of it. All of his tubes are tested before shipping and have a return policy.
