Handing in my iMac for service, how can I clean and clear out all private activity that shows all websites visited and files opened etc?
Apple service technicians don't have the time or inclination to look through your data. They just want to handle your service issues and move on to the next customer as quickly as possible. Your data is far more interesting to you than it is to anyone else.
Nothing in this world is 100% certain, but they handle thousands upon thousands of customer computers. Even if someone was curious, after they've seen a few hundred computers with the same sort of stuff on them, it would get very old. There's nothing special about anyone's data, except in their own eyes.Can you be 100% sure?

It's more than their jobs are worth to go through it. They'll only access what's needed (i.e. if you have an iPhoto issue, then it's reasonable to expect them to open iPhoto). For most hardware problems, they probably won't even boot it into your OS.
Do what I did:
Use Filevault and do not store your key with Apple.
I've seen them run their in-house diagnostic on such a machine. The drive is unreadable but will pass their diagnostics if there is no problem with it. I think the drive won't even boot at all past the initial password screen.
Worked out really well when bringing in the iMac for the HDD recall.

This is a terrible response. You can't be sure of this so stop trying to elude that there is no chance.
OP, in your case I would clone your drive then reinstall the OS. Let them start with a fresh install.
You are able to do a fresh install of the OS if something is wrong though?
I come from window where you get the BSOD the screen of death and if that happens you're done, can't restore or anything. I guess OSX is different which is nice.
Genii have no access to your stored file vault key.

Yes, but I listed the "paranoid" approach. Having Filevault on should be enough.
Storing the Filevault master key with Apple is no problem. You can't actually store the key itself: You enter three security questions, the key is encrypted with the answers to those three questions, and only the encrypted key is sent to Apple. There is no way to get the key back except by entering the exact same three answers to unencrypt it.
If you are paranoid, then you can't know that Apple doesn't send the key to Apple behind your back.
