Regarding a few of the matchups...
Olimar vs Wolf: 6:4 Wolf's favor, Olimar's got some impressive grab combos on Wolf as well as epic range, Bair doesn't seem to work so well due to his...height. Plus all those darned Pikmin X_X
Snake vs Wolf: 6:4 snake's favor, I feel this match up is a little more even than it was, stay in the air to avoid his Ftilt, his Mortars can be reflected right back at him, Bair works extremely well against him. Everytime he uses the grenade drop, you can just grab him and he won't do it much longer. ALong with all that, Snake has a hard time avoiding Wolf's lasers, Oh, and Fsmash > Snake's Ftilt. Still has the weight thing against him, but still, not quite as bad as 7:3. Still an uphill battle though.
Metaknight: 8:2 Dude, this guy is a hard counter to Wolf, You play a good MK and you're gonna lose with Wolf. Metaknight Outspaces you, outpaces you, outprioritizes you, out EVERYTHINGs you. This matchup is insanely hard. As mentioned all of his moves outspace all but laser and Fsmash. And MK's Dsmash > all. I There simply is no move that is faster. MK is a hard counter to Wolf.
What else... D3 seems fine. Although, I've been seeing some pretty gay stuff, obviously the chaingrab infinite D3 can do on Wolf, and I've been seeing D3 Grab -> Grab release -> UpSmash. It appears inescapable, unless Wolf can fastfall out of it... which I doubt.
Falco vs Wolf: 7:3 Falcos favor, if done right , the chaingrab can do 70% per stock, so, per match, that's 210 percent, nearly a stock and a half worth of damage. COMPLETELY FREE. Falco also has an excellent spacing game due to his reflector and Falco's freakin' lasers... Wow. THis is a good sized uphill battle for Wolf.
G&W: 6:4 GaW's favor. I say Wolf can hold his own against GaW, you kinda have to work to get the lasers in, but it's possible, you can still space with lasers. GaW's Bair you're just going to have to get around, but the rest of his moveset is fairly avoidable, his Fair can be outspaced, same with Dair, and Fsmash (You just gotta wait on the Fsmash) And since he's light, he goes down in a hurry. But GaW is tolerable, an uphill battle granted, but not quite as bad as you said.
Luigi vs Wolf - Dead even. Both of these guys have prowess in the air, I'd say just about equal (Due to Luigi's Sex Kick) His Fireball can be an annoying projectile. Luigi has an excellent recovery, and great killing moves.
Zelda vs Wolf - 6:4 Wolf is at a disadvantage here due to Zelda's smashes n' stuff. However, it's not as bad as you said it was. Bair works great against Zelda Lasers do as well, Din's fire can be reflected, Just stay in the air, avoid Upsmash, and you're good.
Shiek vs Wolf - WTF??!?!?!?! 6:4? What're you smoking? O_O Shiek's Ftilt combos can be DIed out of with ease (Except at zero percent and if it's only 1 ftilt_ Other than that, Wolf has a considerably better ground game, slightly better airgame, Shiek can't kill, Wolf's heavy, while Shiek's light and Wolf has Dsmash. I'd say this is about even, maybe even 6:4 Wolf's favor. Nah, even because she can gimp his recovery with needles >_> That gets annoying.
Wolf vs Wolf: 10:0 Wolf's favor, now matter how many times you play the match, Wolf will always win.
Other than all that, I think you're list is nice. ALthough I was a little confused at liggly puff, she's always given me drouble. Her aerials seem to outprioritize mine o.O That just could be me with bad spacing or the other person being a good Jiggly, I don't know, so could you please look into it or something? That was the only one I wasn't sure on.
