This is a much better way of saying one of my earlier points

That was basically my goal. People think differently, so I was trying to restate the idea you expressed in different terms by emphasizing the parallels that can be drawn from Harry's and the Shadow's actions (also JB has expressly drawn a parallet with Lash's sacrifice, so it makes sense that he would have deliberately done the same with the Shadow's actions).

Storm Front
Persecution by Morgan

Dead Beat
Forced to succumb to blackmail to save Murphy's job - which she eventually loses anyway.
Meets a nice girl, Shiela, who turns out to be not so nice.
Lengthy exposure to Polka
Conscritped into the Wardens (more responsibility) without getting a sword

Proven Guilty
Has to resist taking advantage of Molly

White Knight
Accused and/or not trusted by the minor practitioners.

Small Favor
Forced to help Marcone
"Failure to save Ivy" should read: Used as bait to capture and torture Ivy - twice (first to get her to Chicago then to get her to drop her veil).

Turn Coat
Suffers the "pleasure" of white vampire saliva.

Changes
Persecution by Rudolph
Loses precious time in the Erlking domain, severely hampering his plans
Forced to murder the previous WK to take the mantle and is subsequentlly put on display throughout the NN.
Turned into a dog (judging by Mouse's reaction, that wasn't a pleasant experience; also, it broke a Law of Magic)
Finally gets a date with Murphy, only to have it shot out of his hands.
   
Other
Forced to hide his relationship with Thomas
Warm Beer (although personally, Mac is right)
Humiliation of being terrible with Latin

As for the House of M, Mab probably wouldn't have much authority in the mortal world, nor would she see the need;

Yeah, I see her response being, "You have a problem with the local authorities? Well, deal with it. I can't have my Winter Knight incapacitated." If Harry gets locked up, she'll probably just pluck him out of prison into the Nevernever, and then he'll have to deal with being a fugitive. He'd end up living mostly in the Nevernever and/or Demonreach.

Honestly, I think Tilly will be in charge of the investigation so Harry will be okay. He can even tell the truth. "I was shot, fell into the lake and woke up on an island alive, but in a great deal of pain. That's probably all you want to put in the official report, but if you must know, it turns out I was getting CPR from a faerie queen for 6 months until my soul could return to my body."

Luccio seems to be talking about only a part of Maggie Sr.'s life, the part when Luccio knew her. The stories seem completely compatible.

Maggie Sr. started out as an idealist, who was resistant to the White Council and pushy for change (This is the only part of Maggie's life that Luccio is talking about -- pre-renegade/Warlock). When Maggie realized she couldn't change the White Council directly, she probably started looking for allies elsewhere, establishing or joining some kind of Grey Council. Her efforts took her farther down the wrong-path, and the Grey Council turned Black. At some point, Maggie met Malcolm, realized she was becoming or had become a monster, and started trying to make amends. These latter events are the parts of Maggie's life discussed by others.

I don't think Luccio had any reason in the context of that particular conversation to mention "Oh by the way, after your Mom discovered she couldn't change the WC, she went psycho and we had to put a death sentence on her." In fact, I think it would have been rather insulting to Harry, because it would have been suggesting he was headed down the same path.
