I suppose I can't envision exactly how the toothpick will reach the inside of the barrel. Is the opening in the section shorter than I remember? From my experience rinsing and cleaning the pen, I would think that I might be able to touch the flat surface of the plunger, but not the inside surface of the barrel. Am I wrong?
Yup. You're wrong.

But no harm, no foul. Perfectly "do-able."

Also, what effect will the grease have on the ink and the pen's inkflow? How can I ensure that I won't leave too much in the reservoir?
Really takes a very tiny amount. The amount of the head of a pin (not the big plastic round pin heads, but the flat metal sort). Spread it around a bit on the inside of the barrel. Work the piston. If you get too much, you'll know by a glob or line of goop when you pull the piston back. And if that happens, all you need to do is use a cotton swab to wipe out the excess. The stuff is clingy so even a little too much is not likely to "wash" into the nib/feed anyway. I've gotten carried away and the worst effect was it made the ink window look cloudy. Wiped it out. Once you've gotten enough in there to free up the piston, whatever you can wipe out will be excess anyway.
