Good points; perhaps I wasn't too clear on that (updated the original post now). I think most of the players would enjoy more roleplaying, but are simply too used to modules that take them from one dungeon room with monsters/traps to the next. They do the occasional talking to NPCs, but it's mostly wooden and, without encouragement, more often just "I ask the NPC about X" than not.
Noted. Thank you!
Thanks, I'll have a look at those.
I'd prefer to draw on something that's been (more or less) thoroughly thought-out, as I simply don't have enough prep time on my hands to do everything myself.
