That's just how Gingerbread works, you can complain about it, but it's not a bug or LG's fault.
3) Application manager lists all your apps on /data as installed on SD-card, with a useless checkmark next to the titles (which you cannot click or select.)
In my experience, Gingerbread also fails at deleting things properly, so again, it's probably not LG's fault. I often delete something, then instantly get a new mail notification, which is an unread copy appearing in the bin.
