You don't need a Dwight character - but there are others on the show (I don't watch it regularly, but I vaguely recall them) who aren't as charismatic or don't mesh well with everyone else in the office. Maybe it's different because everyone in this office seems to be a pretty young crowd...in the third chapter which I just read, I think Roxy said she's "middle-aged," but I imagine that means thirties, and everyone else seems to be either in their twenties or thirties. Different crowd than if there were some forties/fifties mixed in. Anyway, there can be people who are competent at their jobs, maybe they're able to get along with everyone they work with, but they still may not like them entirely on a personal level and want to hang out all the time and be as comfortable as everyone on this staff seems to be. Surely there's some tension between a few people in the office, right?

As I said, the intern tour really helps with differentiating everyone, and I'm not sure you need to move it up in the story as some people have suggested (I'm not sure how you could easily do that, anyway, unless you put the Intern Tour before the football game scene). I think we're saying that because we're reading the chapters slowly, one at a time over several days, but they're pretty short and I think in a book we'd read them quickly one after another so we'd get into it and reach the Intern Tour and other helpful hints sooner and be able to assimilate them better.

Sparks is an immensely intelligent man who just happens to also have twice the normal levels of joy in his system
HEEHEEHEE. I want a character to say that last part. :D
