How can I make folder View Options the default in Snow Leopard?

It's "show view options" in English. Also obtained by typing CMD+J

Those only apply to the top-level folder. Each folder you open uses whatever you've elected to use as the defaults. Select a folder, CMD+J, set the view as you desire, click on Use as Default button. That setting will be used for all windows that you open in the future that have never been opened previously. All other windows that you opened will retain whatever view you previously selected for them.

If you want to reset everything to one view, close all open Finder windows, launch the Terminal app (/Applications/Utilities/), copy & paste this command into the window that pops up,

find ./ -name ".DS_Store" -depth -exec rm {} \;

hit the return key, quit the Terminal app, restart, open a Finder window, CMD+J, set up the view options as desired, click the Use as Defaults button, and close the view options window. Now, every Finder window you open will have this view.
