Suspension going out. What to do?

[Uber Affe]

I just noticed that my right rear looks lower than the other side. Is my suspension going out? I'm still picking bits off that old super I was selling pieces off of. Should I take the shocks off of that? Is it probably better to buy new stuff?
Which ones should I use for the rear? I'm going with
the 3" lowering kit from the "super low" guys (I forget the name). what about the rear? I'm also going to get that white line bracing kit for the front and rear. Should I get the kafer cup brace too?
HELP!

Thanks for the info in advance,
