What should I use between spikes and wood floor?

I use the Audiopoints and coupling discs that WarrenH suggested. They work really well and they're fairly cheap. Looking at your system pictures, you may benefit from the Audiopoints under all of your components too. I know that I did. I just purchased their Sistrum SP-6 stand, which is even better, if you ever want to change things up a little.

The coupling discs are $6.99 a piece at www.audiopoints.com, so basically $56.00 and you're all set.

Er, don't use pennies. Tried that with a pair of ProAc RS2s and Target RS4 sand-filled stands. The spikes punched through the pennies and still marred the floor...
