How do you move applications to SD card? For that matter how do move files to the SD Card and access it to see what is on it.?
You won't be able to move them until Froyo (Android 2.2) is released and then the app developers will need to make them compatible before you can move them. There are ways around that but it's more trouble than it's worth. As for the second question, you can download an app like Astro File Manager to view the contents of the sd card.
es file explorer is good too. apps like these allow you to view the folders and files on the device and the sd card in sort of a windows explorer type of view.
