Anything close to Limewire that is safer?

Not really.
All P2P like Limewire or Frostwire or other P2P clients that involve file sharing are dangerous, who know if what you were downloading was infected, that's why P2P is one of the biggest sources for getting infected.

I am wondering why my CPU usage is so high on Vista can you explain?

You have a lot of junk running at startup.

Post a new Hijack This log and we'll stop some of the un-needed things and take some stress off the processor.
