I have both contenders and duds who may contend next year and marginal contenders. My answer for Bonds for all 3. I would never give up a Rook 1 or FA 1 for him. His career is possibly over. If you think he's going to put you over the top this season maybe a rook 2 and FA 2 in a 20 team league. If it's me though I wouldn't touch him. 95 games is not worth a FA 1 or rook 1. If your trying to trade him and anyone offered you a FA 1 or a rook 1 I'd jump all over it right away.
