Strike the T1 off the list, they're not closed, and although they're very nice sounding they aren't going to fit for your use-case scenario.
I've gone through quite a few of the high-end closed cans - W3000ANV, Ed8, Sig Pro, T5p, Jaben-modded T5p... Of all of those I still have the T5p, Jaben-modded T5p, and W3000ANV.
The W3000ANV is a very special can, no doubt. It isn't quite so well suited for portable use IMO, since you'll want to baby those gorgeous woodied cans, and they tend to fit fairly loosely which isn't quite ideal on the go (you can work with that to an extent, some people use rubber bands to increase the clamping force, or bend the band at the top for example). They also don't isolate quite as well as others, which may not be entirely to your liking given your specific needs. I don't tend to think of them as a 'rocking can' either, but YMMV.
I really like the T5p for rock, which I listen to a lot, although they are a bit bass-light (opinion varies widely on how satisfying the bass is, but the consensus opinion is that they are a bit bass light nonetheless). For myself I'm happy enough with their bass. Vocals aren't particularly forward in the T5p generally, so they may not do female vocals as well as you might like (I listen to female vocals, but not really for portable listening sessions, so I can't be more definite than that for now, will try some out later and see). They are great for classical and all the other needs you have though.
The Edition 8 is also nice, I had no trouble with comfort there, although the inner dimensions of the cups will be too small for those with larger ears. Their sound signature is quite nicely suited to rock, but for me I wouldn't particularly rate classical as one of their strengths with the U-shaped frequency response. You might want to also consider the Signature Pro from Ultrasone, bit more suited for portable use than the Ed8 with a removable cable, cans that fold flat and a portable carry-case included, and probably better suited overall to your needs sound-wise.
No experience with the Fostex TH-900, but my brief perusals of the thread for them in the high-end forum suggests they could be good for your needs - my impression reading there was that they are very detailed, but still have some fun slam to them. Might be worth your while to read that thread a bit and ask for feedback there, lots of the people posting in there will have experience with multiple headphones amongst the ones you're asking about.
Similarly no experience with the Momentum, so can't advise there.
I'd get an amp for all of these, although some like the T5p and Ed8 can be driven quite satisfyingly from portable sources like iPhones (what portable source are you planning to use?).
