Gasol and Bryant both played 38-plus minutes for the Lakers, who reached 60 wins for the 11th time in franchise history but the first since they went 67-15 in 1999-2000.
Los Angeles pulled within a game of Cleveland for the NBA's best record, and Jackson definitely wants the Lakers to have the home-court advantage throughout the playoffs.
"We have to make an attempt for it. I wouldn't feel good about it, even with these players, if we didn't. We really don't have to threaten our well-being by doing it, I don't think," the Lakers coach said.
So winning against possible postseason opponents also makes a statement?
"I think it certainly does drive home a message. It's not the end, obviously, the games have to be played, but teams have that in the back of their mind,
'Here it goes again, we're going to lose again.' That's an issue I think that's important, to always have that kind of dominance."
The Lakers did, but they had to push and shove for it against Houston.
The game was gritty from the start and three technicals were called before the first quarter was over
- on Bryant, teammate Derek Fisher and the Rockets' Aaron Brooks.
"They're a tough team and we've had our problems with them in the past and during the regular season," Bryant said. "I wanted to send a message to my teammates and to the referees that we're here to play, we're not going to be out here just kind of going through the motions.
"If a guy's going to grab my shirt, I'm going to let you know about it. It's important to come out with a sense of urgency right from the top. We're fighting for a bigger prize. It's going to get chippy."
Ron Artest had 21 points for the Rockets, who slid into fifth in the Western Conference, a half-game behind Portland.
Bryant hit consecutive 3-pointers with less than five minutes remaining to give the Lakers an 11-point lead and Gasol made four free throws down the stretch.
Yao Ming had 16 points, 10 rebounds and six blocks for the Rockets. Luis Scola scored 16 for Houston, which was swept by the Lakers in the season series for the first time in seven years.
