So who are these guys?

Yeah, who hosts it?

The show is co-hosted by Jonathan Messinger
and Jeremy Sosenko.

They like to stress that The Dollar Store is more about the performers than the hosts. If you're curious about who they are, however, you can spend some time at Jonathan's website, Shoot the Messinger, or his book thingy featherproof. Or go see Jeremy at the former ImprovOlympic as an integral part of the Late Night Late Show.
