Just checked my connection at work and have a 20KB upload speed, which has been normal over the last 4 years I've been here, so I don't see any change in the isp policies, but will check from home to see if there's a difference there.
As for legal torrents, check out
http://beta.legaltorrents.com/ for a start. There are plenty of places to get legal torrents from, you just need to look. I personally download a lot of music from unknown bands, and while there's a lot of crap there, there's also the gems that I wouldn't have found if I wasn't looking.
