As far as Kaman goes, he's listed as day to day, and should be back this week. Kind of depends on what you need when you're deciding whether to start him, Diaw, or Raja. They all bring different things, and bring them pretty well, so you should base your decision off of what categories you're weakest at.
And lately he's been putting up much better numbers. Two double-doubles in the last two games. I think he should keep that up and be a pretty consistent double-double over the rest of the year. Once he gets back from the injury, that is. He should be back within the next few days, Your best bet is to keep checking his profile on Yahoo, and see what they're saying about the ankle.
