OKay, the inner Roll pin that keeps my breech block in place is starting to work it's way out the left side of the slide ever so slightly. What do I do about it? Do I have to take it to someone or do I just pound it back in myself or what?
 
Use a roll pin punch (or just a regular punch if you don't have a roll pin punch) to knock it back in. I did it once during advanced officer training for a classmate who was with the D.A.'s office. Our instructor for that day was a First Aide/CPR instructor. He wasn't very happy about "gunsmithing/armorer work" being done during a break in his classroom. Well, it's government work and we were on our time so why not?
 
You should replace both the outer and inner pins. The slop from inadequate tension allowed by loose pins will eventually necessitate a much more expensive fix to your breech block [if it isn't already damaged].

When you replace the pins, make sure the outer pin is located with its gap at 12 o'clock [oriented to the top of the slide] and the inner 180º opposite. And do use the proper cupped roll-pin punch...it won't damage the roll pins as a regular pin punch will.
