Drive Cloned ... Upgrading to Leapord

Sorry for a question that has probably been done before

I want to upgrade to Leapord but save all my bookmarks, settings, dock items, passwords, apps etc.

SHould I do a basic upgrade? I also just bought an external drive and have my entire current machine cloned via carboncopy cloner.

I was wondering if I could do a clean install and then use migration assistant on the external drive ? Would that give me EVERYTHING I currently have or should I go ahead and do a basic upgrade.

Thanks

Where would it archive to? I don't have enough room on my HD.

Can I connect an external HD and use that as an archive location?

Wouldn't it be just as effective to do a delete and install and then use migration assistant from my cloned drive?

The main thing is I need my apps, prefs, bookmarks, dock items etc to look the same.

 

I hate to bump my own thread but could use some advice
Thanks

*sigh*

Anyone? I don't want to bugger up my machine
