This EP's real good. The latter 2 RIYLs seem a little far-fetched. I would link to my review but it hasn't been posted yet. :(
Maybe a '00s vibe. I have no idea what '90s bands you'd refer to, except that the Matt Vincent-sung bridge in question sounds more to me like Brand New than anything (which could be '90s in a roundabout way).
I'm not really sure how to describe it. It's in more then one song. It's like there's a "grunge" guitar part buried in the mix.
