I've added maybe a dozen fonts at a time without a problem, but since I stick to only a few fonts, I removed them after testing for my favorites. So I don't think there's a limit (other than space on the reader of course), but I would think it would get annoying fast to have to scroll through 3+ pages of fonts to select the one you want.
As for the space at the bottom, there are some pages in the same book which will look like there's almost a full blank line, but it's not really quite enough for another line of text to fit on. Is that possibly what you're seeing? Did you try adjusting the font and size to see if it gets any closer to the bottom?
