There's no real answer in the series to the first part about whether having the Eternal Mangekyō affects the power of chakra, but I recall it being said that the eyes possess greater dōryoku (ocular power), though what that means in practice is anyone's guess. As for the second part, yes, dōjutsu do carry some of their original owner's chakra. Ao was able to recognize Shisui's chakra in Danzō's right eye, and Madara's Rinnegan were said to contain chakra so powerful that they carried a risk to anybody who implanted them.
