I just used Disk Utility and formatted the entire drive to HFS extended journaled format. It's very easy to use. I did it while booting off the Leopard install disc after putting the SSD in. Setup begins. One of the first screens you get to (before the install begins) has a menu at the top. Find Disk Utility. Go there and you'll see your drive. Highlight your drive and find the button to erase it (or format it). You'll see a list of possible formats. Pick one that says either Mac OSX extended (journaled) or HFS extended (journaled) - I forget which it says. There is an option to choose a case-sensitive format. You can do that if you want - I did not. Then start formatting. It just takes a sec. Then exit Disk Utility and continue setup.
