a) These are the "Countess" drops (also see the ReadMe.txt ;)) :
Normal difficulty: up to IO (rune 16)
Nightmare difficulty: up to UM (rune 22)
Hell difficulty: up to LO (rune 28)
Good runes can drop everywhere, including simple chests. However, Act bosses, superunique bosses, quest and random bosses, and champions, have the best chances to drop an item from the "Good" category, which includes runes.
b ) Rune drops got nerfed a bit, but good runes still drop plenty (compared to Battle.net). I have just played my Werewolf Druid through the last revision of my MOD (which will be released this week). He's now in Act 5 Hell, level 85 and wields a "Silence" Thunder Maul. The "Countess" in Hell dropped the required VEX rune during the first quest run ;)
