Things I don't fully understand:

13a is kinda baffling. My best guess, which I don't believe, is that the answer is MORITA, obtained by taking MORTICIA, reversing IT (though I believe the actual name of the character this would be referencing is "Cousin Itt", with two Ts) to get MORITCIA, removing C+I ("see yours truly leaving") to get MORITA; "early player" would then be the def; there are many Japanese people called Morita, some of whom play games or instruments, but none of them jumps out at me as being defined by "early player".
I'm not sure who the second def in 23a is. Fielding's title character, perhaps? (First is Amelia Beauclerc. Third is indeed the dictionary definition of "amelia".)
21d is clearly DRACULA; D. felix and D. bella are two species of orchid, so "Felix and Bella, perhaps, flowers" can be the definition, but I don't understand the wordplay. I wondered about something to do with Dranunculus, a genus of lilies, but don't see how to make it work.

Things I didn't fully understand but now think I do thanks to helpful comments from people cleverer than me:

It was clear that 2dn is a spoonerism of something WON but I couldn't figure out what. oAlt points out the existence of the "Solf Circle", a group of German intellectuals opposed to Nazism.
I was mystified by the gentlement in 26d. oAlt points out the existence of a Buffy episode titled "Hush" featuring adversaries called "The Gentlemen" who take away people's voices.

Things I said "I don't fully understand" about in an earlier version of this answer, but that were really more quibbles about clue construction (but it is possible in each case that I am in fact failing to understand something and there's nothing wrong with the clue):

6a,29a seems like the "following" is backwards; KITH is following KINE, not vice versa. Also, I can't help wondering whether there's some sort of reference to the phrase "kith and kin" going on here, but if so I don't quite see how it works.
18a seems to be an anagram with no anagram indicator, and I'm not sure what "reading" is doing in the clue.
17d seems like it's missing an "in" in the definition; Carmilla is one of the stories in In A Glass Darkly by Sheridan Le Fanu.
