Great episode, Bob. Love the comic-centric ones.
As far as the Marvel Universe goes now and Captain Marvel, there's actually nobody currently using the name.
The last person to use it was Noh-Varr, as you mentioned, but he's currently known as The Protector. (Honestly his new name and costume aren't nearly as interesting as when he was on the Dark Avengers.)
I believe Monica Rambeau is still active but hasn't been featured in a book in a few years, and goes by the name Photon now, anyway.
Although, it's worth noting that the original (Marvel's original, that is) Mar-Vell actually appeared recently in a Chaos War tie in called Dead Avengers, in which several Avengers that had been killed (including Deathcry, Doctor Druid, the Swordsman, and the female Yellowjacked) returned to life for a short time because of all the shenanigans occurring in the underworld.
Anyway, if you guys like these comic centric episodes, you may just enjoy my show as well. (Link in signature, excuse the shameless plug.)
Excelsior!
EDIT: Hmm, signature not attached. Here's the link, anyway.
