I've not done that second part,  but have tried to get something of a grip on 
what's out there,  see my parts pages at 

http://yourpage.blazenet.net/rtellason/parts.html

and look over the generic parts page.  That stuff all started out as a way for 
me to organize info that I have on hand here,  and I put it on the web 
thinking some folks might find it useful (though I expect the transistor 
pages are probably more so).

Roughly that stuff seems to be either bipolar or CMOS,  but I have no idea 
what the differences are between some of the series,  or how they fit in 
terms of the overall picture -- where 74F fits in for one example.  One of 
these days maybe I'll get a grip on that whole issue and put up a page about 
it...
