Yes; the bonus attack for Martial Arts and the bonus attacks from Flurry of Blows all add your relevant ability modifier to damage. Unless an ability specifically says you don’t get it, you always get it.
How do you calculate unarmed strike damage?
Instead of using a weapon to make a melee weapon attack, you can use an unarmed strike: a punch, kick, head–butt, or similar forceful blow (none of which count as weapons). On a hit, an unarmed strike deals bludgeoning damage equal to 1 + your Strength modifier. You are proficient with your unarmed strikes.
Do you add proficiency to flurry of blows?
You don’t add your ability modifier to the damage of the bonus attack, unless that modifier is negative. However, monks do not get this fighting style.
What happens when you use flurry of blows?
Basically, when you make additional attacks using Extra Attack or Flurry of Blows, all the attacks are done separately. With Flurry of Blows and no Ki points spent, you already make two attacks on the row, which must hit and damage the target separately. This is similar to Extra Attack applied only to your unarmed strike.
How does flurry of blows interact with multiple attack penalty?
As a monk, I can make a Flurry of Blows action that lets me make two unarmed strikes with one action.

With Flurry, I’m making 2 attacks with 1 action.

What does a flurry of blows do in DND 3.5?
I should point here, D&D 3.5 FAQ itself isn’t without issues, so should be employed carefully. Flurry of Blows consists of only those bonus attacks class-feature itself gives you, and all other attacks in a full-attack a monk makes are just regular attacks.
