Let's say I have N particles in a box and I want to find out how many particles have speeds between v and v+dv. How do you use the Maxwell-Boltzmann distribution to do this? How do I find the sum of the speeds of every particle?

Average speed is calculated by adding every particle's speed together and dividing the result by the number of particles.
