Great input. I have since received a response from LastPass re this matter and they have given me a step by step guide. It appears that when the App is launched from the iPad App I am given access only to my Pass Word Vault. If I then follow their instruction on how to download and install their Bookmarklets from the LastPass site, all will work after the installation and syncing with the desktop via iTunes..
Now all I need is to find the time and access the computer without have to fight the wife for it. ;-)
