I have a haynes manual for my car that shows the two points on the front cross member as a good lifting point as shown in the pictures. I alternate a little bit at a time between the two floor jacks (even and steady) until I get enough height to insert the jack stands.

I would be scared to use the hockey pucks on a curved surface, anywhere the hockey pucks don't have complete surface contact would be dangerous.

Hopefully you'll get other responses on how to lift your car with the jacks and stands you have.
