"In the case of the quarterstaff, each end counts as a separate weapon for the purpose of using the flurry of blows ability. Even though the quarterstaff requires two hands to use, a monk may still intersperse unarmed strikes with quarterstaff strikes, assuming that she has enough attacks in her flurry of blows routine to do so."
Given that Flurry of Blows only adds a maximum of two extra attacks, then if 'flurry of blows routine' refers only to those extra attacks, how can you ever have 'enough attacks in your flurry of blows routine' to intersperse unarmed strikes with quarterstaff strikes?
One unarmed strike and one quarterstaff strike isn't "interspersing".
If a Monk 15 is using a quarterstaff, he gets three attacks from BAB and two extra attacks if he uses Flurry of Blows. Does he get to add 1.5x Str bonus to the first three attacks, and only 1x to the extra attacks? If only the extra attacks are considered 'part of the flurry of blows', then the first three attacks should follow the normal rule for attacking with a two-handed weapon, right?
If every attack gets 1x Str bonus, though, it means that every attack is "part of the flurry of blows", and thus using non-monk weapons at all in the same full attack action as a Flurry is prohibited.

Trips are defined as an unarmed attack.
Disarm can be done as an unarmed attack.
The monk Unarmed Strike class ability also refers to itself as an "unarmed attack" (Page 41, 1st column, last sentence).
So it seems that a monk's "Unarmed Strike" is also an "Unarmed attack", and you can freely substitute Trips when unarmed, or when armed with a monk weapon that can trip. You can also freely substitue Disarm attacks when unarmed or fighting with a monk weapon.
The only one that seems to be handled differently is Grapple, and that's more an inference than a direct statement. (The monk unarmed strike ability states "she has the same choice to deal lethal or nonlethal damage while grappling [see page 156].")
The grapple description doesn't make any direct references to grapple as being an unarmed attack, but most of the examples and flavor text show it being done unarmed or with natural weapons (if you have Improved Grab). Yet you can increase your grapple damage by using a manufactured weapon (armor spikes add +1d6 damage on a successfull grapple check).
Grapple seems to be it's own little combat sub-system, different from melee or ranged combat, with it's own modifiers (size modifiers work differently, and you don't use AC or attack rolls, just opposed grapple checks).
The real question is, does a grapple attempt count as an unarmed attack for the purposes of a monks flurry ability. By the text of the monk class, the answer seems to be "No" but I'm really not sure if that is the intent.
I'm willing to be convinced otherwise by a reasonable arguement (as I play a monk grappler sometimes), but I haven't seen it so far.
