Is utorrent a good torrent program,recommendations? and can I get sued for?

(Almost) Any program that allows transferring of files between two computers involves the other computer knowing your IP address. Nothing -- not even sending a different IP to the tracker -- will change this. The MPAA/RIAA et al get IPs by connecting to the tracker and attempting to connect to the nodes involved. Those it can connect to are now no longer obscured. There is absolutely no protection against this; no matter what, this will be the case. It is a by-product of the protocols that run the internet.

There are some programs out there that can protect you from this method of IP discovery. They are called darknets, and tend to be a bit slower and sketchier in nature than the 'open'/non-anonymous P2P systems, like bittorrent.

That said, IF it is true that you only use it to download fansubbed anime, there is almost a 0% chance of you getting sued (assuming it does not have a distributor) - the Japanese companies tend to be liberal with derivative works like fansubs, as it is good market research as to what will fly in the West and be worth bringing across the ocean. If there is a distributor in the states, the file transfers will go less legit (fan sites will stop directly posting the torrents, etc), but I have never heard of legal action being taken.

Oh, and changing your IP address will do nothing. Your ISP has logs of who is in control of what IP at any given time, and will provide it upon subpoena to askers.

Limewire is as easy to track and even easier to prove infringement than BT, so thats no improvement.

 EDIT: Since it was brought up, encryption will also do nothing to protect you in this aspect.  It will protect you from snoops along the wires (like ISP packet shapers), but for what the MPAA/RIAA do to track infringers, it will do nothing; at some point the data needs to be decrypted, and by making themselves the place where it is decrypted the RIAA is able to track you just as easily as without.  So don't count on encryption (which Azureus, µtorrent, bit-tornado, and other programs all use the same protocol for interconnectivity) to protect you from lawsuits.
