Since it's a folder, hold down the Command and Option keys, then drag the folder off the Bookmarks Bar. You'll get a confirmation dialog saying "Are you sure?" Just click the Delete Folder button in the dialog.
Holding the Command and Control keys keys down gets you a contextual menu that allows you to edit the name of the folder, edit its contents (jumps you to the Bookmarks window to do that), delete it, copy it, and a few other things.
iCloud syncs Safari bookmarks as well as Keychain passwords across your Macs and iOS device today. Simply sign into iCloud on your Macs, and configure both "Safari" and "Keychain" in iCloud settings in System Settings. If you are having trouble getting this to work, check here: http://support.apple.com/kb/TS4001
In my experience, iCloud is not as quick, nor as persistent as is Google Sync. It can often take many minutes to get updates, and sometimes it seems to fail outright. This has been improving for sometime now, but IMHO, its not as good as Google.
Alternatives include Xmarks and LastPass. XMarks syncs bookmarks across everything, whether you use Safari, Chrome, Firefox, Mac or Windows. Highly recommended. The Safari support is a little odd, due to Safari not having a similar plugin capability. Lastpass manages passwords for websites, recommended as well.
For your use case, of syncing across Chrome and Safari, ipad, etc: XMarks doesn't work on iPad Safari. You can use Chrome on iPad, and get your bookmarks synced from Chrome, but this doesnt work for Safari. To get Safari to share the same bookmarks:
- On your Mac, Install XMarks for Chrome
- Create XMarks account, and sync your
bookmarks
- Install XMarks for Safari on Mac
- Sign into your account, and
allow XMarks to overwrite your Safari bookmarks
- Make sure iCloud is
syncing Safari Bookmarks
- Ipad/iPhone Safari will now contain same
bookmarks as Chrome.

Which ever way you look through the Bookmarks in Safari, it will offer you the option a sub menu to "open In Tabs"
Example: From the Bookmarks menu bar.
