Regarding the display-driving 7408's, what is the reason for not using LS versions ?.

The resistance of the output stage is different, and I speculate that the input capacitance helps the 74ls157s latch the segment data. I don't however know of anyone whose tried LS parts so I don't know specifically that they won't work.
