Welcome to HW and our little corner of the world.
The facts are that you now have diagnosed PC, based on a biopsy a Gleason 6, low core %, which on the surface sounds good. The only problem I see with the Active program is that it is always a gamble. You have to compensate that a low grade gleason 6 is all you have for now or in the near future, or that the biopsy missed some more serious cancer areas in your prostate. Often, after surgery, if one chooses that path, their Gleason is upgraded, seldom is it downgraded (though it has happened that way). If you really have some Gleason 7 in you or higher undected by your biopsy, then waiting any serious length of time is not a good thing in my opinion.
Right now, as Tudpock said above, you have more primary treatment options availabe assuming your PC is as low grade as indicated. Later on, if it grows, or if it is worse in its known nature, your options will be less.
The whole trick is taking care of the cancer in the best manner before it can escape the prostate itself, and that is a big unknown to you the patient at any given point in time.
Not telling you what to do, but I would check the PSA again in no more than 3 months from the last one, and if it has increased by .35 or higher in that short a time, I would think at the least, another biopsy should be done, to make sure that it is still just a Gleason 6 situation.
With your current stats, and your prostate size, you could be a good candidate for seeding. I wish you luck as you think through your options and plan ahead for your bout of PC. One advantage of having surgery, either robotic or open, is that usually you will know the true extent of your PC once the prostate and other bits/pieces have been removed and you see the results of the final pathology report.
We are here for you, whatever you decide to do.
