Hi Todd--congrats on your new Baby!
As to Aps--Most people seem to stay in the Wide-Open (f2) to f8 range (at least with the Double-Glass, Single-Glass and Plastic Optics). Many Benders are more fond of one end of the spectrum than the other. Some really LOVE the dreamier, more abstracting and shmeary qualities of the wide-open or larger aps (I'm one of them), while others prefer the greater area of focus and (relative) sharpness of the smaller aps. Play with them all and figure out what fits your style.
The Sweet-Spot changes size with the apertures--check out the Optic Comparison page for visual examples:

If you're interested in the more technical/cerebral/conceptual aspect of Bending (much of which is beyond my feeble mind), here's an interesting discussion that was had here on the forum a while ago:

As to the little hole in the aperture tool--If you're talking about the one in the bottom of the aperture storage area (mine doesn't have an "L" next to it), I think it's just a way for the air to escape when you put the cap on...and I have no idea what "L" stands for...
Hope this helps and have a great day,
Johnny Crabcakes
