Nah, it took me until the fifth or sixth volume to realize it, so you're not an idiot. As for his Baskerville mutt...eh, I'unno, might be in the manga. *shrugs*
And I think they made Integra more scary than she should have been in the anime. She's a lot more...human...in the OVA, and the manga. Like when Seras started going insane killing the ghouls that the Valentine brothers came in with, instead of being all sharp with her, Integra practically begged her to stop. And then she was really hurt about all the people that died and it definitely showed on her face when she was going to the funeral. So...nah, I don't find her scarier. Just tough.
Ehh...I prefer it actually being spelled Alucard, rather than the romanized crappy version. No offense, but Alucard actually goes along with his name's anagram. =P
