Those statements aren't contradictory; "if you do have Java installed" refers to versions of OS X earlier than 10.7 and to those users who've elected to install Java in 10.7 on their own. (That article has been cleaned up; the first time I looked at it it said that Apple had dropped Java in Snow Leopard as well as in Lion.)
I wonder why your iMac has got both Lion and Java?

Here's a pretty much useless description of what the trojan does:
First it will ask for an administrator password, and if supplied it will install its payload into target programs within the /Applications folder. However, if no password is supplied, then the malware will still install to the user accounts where it will run in a more global manner.
If you've installed the update and haven't been doing any questionable browsing lately, you're probably safe.
I hope somebody will be able to expand on that.
