When Houston wins then Utah is going to have nothing to play for. Favors is already hurt so I doubt he would play if he didn't play in their last 2 games when something was actually on the line. I think the other starters will play but it is tough to say how many minutes and the motivation probably isn't going to be there after finding out you aren't making the playoffs 15 minutes before tip.
I got over 41 wins for Utah on the season so hopefully they try to win, but on Kobe night the Lakers will probably be playing harder than they've played all year, crowd will be into it, the refs for the game might be Fox, Fisher and B shaw. Tough to see Utah showing up and matching intensity.
