Marius & Sulla - Chronology Question

i have questions about the chronology of the mithridatic wars and how it intersects with marius and sulla's civil war. from my understanding:

1. marius and sulla fight together in the social wars
2. sulla is sent to fight mithridates
3. marius takes over rome and takes the command away from sulla in terms of legislature
4. sulla marches on rome

(this is where things get dicey for me)

-sulla puts forth reforms in the senate, makes himself dictator -sulla heads back to the front, ends mithridatic war with a pretty lenient truce -marius again takes over rome. marius dies, cinna is killed. ??? takes over? -somehow sulla regains the dictatorship -sulla comes back to rome and rules -sulla resigns

QUESTIONS:

-is this timeline correct? -when did pompey switch from marius to sulla? -when did the battle of the colline gate take place? -when did sulla sack athens? -when did sulla have his proscriptions carried out?
