According to Marc Topkin at the St. Pete Times [Thanks, Adam] Justin Ruggiano and Leslie Anderson passed through waivers and remain part of the Tampa Bay Rays organization. This puts them both in roughly the same status that Elliot Johnson was at this time last year. They'll probably go to spring training as "non-roster invitees", play their hearts out, start the season in Durham, and then we get to see what happens.
I'm a little surprised that Ruggiano made it through the waiver process. My only guess is that other teams were just too close to spring training to give up a slot on their 40-man.
