I recall going through the Hoogendorn analysis and also the first part of the IM Lenderman(?) video about the Smith-Morra (approx. 25 min. long) I think his name was.
Top-tier players as black generally play Nc6/e6/a6/Nge7/Ng6.
I am not sure if this is the most stringent defense for Black though; I recall reading a review on the Silman site that delaying the queenside N development somehow takes some of the strength out of an eventual e5 and note that the timing of Bb7/Qb6/Nd7 or c6 I think are critical. The book review obviously does not go into lines.
Black scores well with it (Nc6/e6/a6/Nge7/Ng6) defense because white usually doesn't know the correct plan for dealing with the Nc6/e6/a6/Nge7/Ng6 though.
Here is a game (posted in the fora) before illustrating strong Black defense against a white setup that I believe is incorrect. Generally the Bc4/Qe2/Re1 setup is best but not against the Nc6/e6/a6/Nge7/Ng6 defense.
White's bishop doesn't belong on c4 if d6 hasn't been played; otherwise, it is just hitting brick. So better is 6. Bf4 instead of Bc4 in your game, at least according to the Lenderman analysis I think is best.
If Black plays d6 then Bc4; if not then Bd3 though perhaps development of the bishop to d3 is better delayed after Rc1 which is likely in most lines. Of course white plays e5 at some point.
Compensation for the pawn comes in the hot c and d files.
Ng5 seems premature although Bxh6 is a nice find; I am sure Black likely had better defensive resources before then.
I know that you have seen both analyses (chessville/Lenderman) before if I recall correctly so you may already know much of what I have said.
I have played through all the chessville lines and the analysis is good although incomplete, though sufficient for introductory purposes. It's worth going through if you are considering keeping the Smith-Morra as a permanent part of your repetoire.
The Smith-Morra is good for quick wins; white has great chances because it is very easy for an opponent to awry. The lines and ideas are very, very easy to learn as white.
However, if your attack doesn't work you are still down a pawn, but most people really don't know the lines, even very strong players. Also, almost all the players who I have faced almost always decline the gambit w/d5 and I do not like all Alapin lines.
