GS should finish off the Rockets and KIM. Extending the series isn't going to heal Curry faster, and the last thing you need is for Houston to get any confidence and start playing like they care. The more games played, the greater the chances for injuries to other players. A couple days could give the Dubs time to better adjust to Curry being out, but I have a hard time believing they beat the Clippers without Currry.
Livingston doesn't space the floor like Curry does, and that alone will change the entire dynamic of the game. Barnes will have a big opportunity to put himself in a position to make major bucks this offseason, as he seems to be the guy most capable of playing at a higher level and picking up the slack. The Rockets don't even look interested, but the Clippers will be motivated. Curry will be re-evaluated in 2 weeks, which means he prolly won't be cleared until that point. With a bad knee, and ankle, he won't be conditioning, and he will have to shake the rust off. That doesn't even take into account the mental aspect of getting over an injury. If the Warriors are smart, they rest Curry until he is 100%. If that's in the next round, western finals, NBA finals, or next year, so be it. Dubs had a great season, and if Curry can get healthy to the point where there's no risk of further injury, play him, but you don't jeopardize a guy like this career long term for a chance to maybe win a title this year.
