So last night I disassembled my PF9, cleaned it and attacked the project of sanding a few areas, according to the following website:

I guess I wasn't paying attention when I removed the screw for the extractor.  This released the tension on my firing pin, it ended up sticking out the back side about 1/2 an inch.  I noticed this when i tried tightening down the extractor screw, and it wouldn't go in all the way.  I pushed the pin in and was able to tighten the screw.  Obviously the pin nor the spring flew anywhere, there was still tension on the pin from the spring.
 
I'd like to de-bur the firing pin holes with a drill bit, as explained in the provided link.  For the life of me, I can't figure out how to actually remove the pin and spring from the slide assembly.  Am I blind?  If anyone could maybe explain how to do it, it'd be greatly appreciated!
 
Also, any recommendation on a dry lube to use for the firing pin, and where to purchase it?
 
Lastly, step 12 of the provided link is a little foggy to me:
 
"12. no pic. Using a drill bit a few sizes larger than the firing pin hole, lightly chamfer the firing pin hole on the breech face side. This will make it more difficult for debris and grime to build up."
 
So somehow I should be able to position a drill bit at the breech side, and I'm supposed to, I dunno, drill a light recess around the existing hole?  That's how it sounds to me, I just want to make sure before I take that on.
 
Thanks in advance!

That step you use a drill bit by hand on the breach face side to give the firing pin hole a slight chamfer.  
GL is a member here and maybe he'll see the post and offer his advice.
 
I use some Hoppes dry lube, I think I bought it at my LGS or Cabelas. Some KTOGers use silicone spray also.

Looks like billjohnso20 and CJP32 have got you covered.
 
A very light coat of gun oil or CLP on the firing pin and spring will work fine too.
 
It is a lot harder to write instructions than it looks.  
When I already know how to do something, any drivel I type out makes perfect sense to me  
 
Best, GL

I just fluffed and buffed mine as well, and it seemed to be in good shape too. No real burrs in the slide  grooves, etc.

I wonder if the tip of the fp maybe sharp rather then rounded and is causing the brass in the fp channell? It maybe scraping some shavings off the primer and pulling them back into the channell.My pin is rounded and I have never observed any brass.What do think?

As far as brass in the FP channel, mine has only done it once. I cleared it at the range. A single piece of brass had gotten in the hole. My firing pin isn't sharp or overly pointed. In fact, IIRC, it is the extractor that creates the brass pieces that can sometimes get in the FP channel. I have even wondered if the ejector might also play into this equation. I do know however that KTs are not the only ones that do it. My wife had an XD that produced copious amounts of brass filings for the first 500 rounds. Also, the two 40S&W PPS's we own also produce small amounts of brass particles. All it takes are for these pieces to migrate and any gun can experience a light strike. I've even known of 1911s doing the same thing.
