BenSam,
It's a confusing time when one is first diagnosed. PC is different from a lot of other cancers in that there are choices for the patient to make, and the choices (other than Active Surveillance) are irrevocable. The thing that's different that's in your favor is that it's typically slow growing, especially likely given your current diagnosis. So breathe, and take your time with this.
It's a very good idea to get a second opinion on your biopsy slides from Bostwick or Epstein, even if you have to pay out of pocket. There are links in the sticky Jim referred you to.
I won't throw a lot at you yet, but I'll try to address a few statements you made.

5/ 12 samples showed cancer (25%, 25%, 40%, 50%, 60%) all on right lobe, thus I am T2b
No. Staging is irrespective of the biopsy. It is usually based only on the DRE. Most men are clinical stage T1c - unremarkable DRE.

One perineural invasion identified on 60% core (how significant is this??)
Not significant at all. It's a very common finding on biopsy that doesn't much affect the prognosis.

Am I low risk or low medium risk?
Assuming your DRE was unremarkable, you are low risk. That means you qualify for Active Surveillance (on many programs) and all the radical therapies: surgery, SBRT, IMRT, LDR brachy, HDR brachy and protons. Which is the best for you depends on you, and no one can answer that for you. You have to do a frank self-assessment to figure out what's most important to you, and weigh that against the risks and benefits of each treatment. I did a lot of soul-searching, a lot of information gathering, and a lot of interviewing of doctors (6, I think). BTW - I was the same age and single at diagnosis, and maintaining potency was my most important consideration, given that all treatments are equally good at curing low risk disease.
