#1: I use a K3 with its "regular" font set to its 3rd from the smallest size (when the ebook doesn't force something different, rare in MOBI format), line spacing "large", and Words per Line set to default. This works out to about 10pt type with an additional 3-3.5pt leading (total line to line space 13-13.5pt. This yields a decent text height and a proper number of characters per line (see #3)
#2: Using a smaller type size should have no impact on your eyes, only on readability. If you have eye difficulty (eyestrain, tiredness, ...) you need to have an Optometrist check your eyes. You probably need corrective lenses.
#3: It has been proven through extensive testing that columns of text (read: classic book page layout) are the most readable when the line length is somewhere between 35 and 45 characters, depending somewhat of the characteristics of the font. Longer lines make it much harder for your eye/brain combo to follow the line and to correctly return to the beginning of the next line when you've finished with the first line. Overly short lines reduce readability due to the overly frequent need to change lines. Increasing the line spacing can somewhat mitigate the problem of overly long lines, but doesn't cure the problem. Also, fonts with a smaller x-height (height of the common lower case letters that don't have an asender or decender relative to the point size) require less line spacing. The Kindle's "regular" font has a modestly large x-height and, in my opinion, benifits from slightly increased line spacing.
