Release dates are in the official discography.

Yes. SS501 also promoted through a sub-unit made up of some of its members. The main example is the project album "U R Man" released in November 2008, which featured three members: Heo Young-saeng, Kim Kyu-jong and Kim Hyung-jun. Because the lineup differed from the full five-member group, fans often enjoyed the two as separate activities.
