So if some one steals my computer they their is no wallet.dat for them to get!!!!! or use or see.

Oh. Minor detail. Cheesy

You are actually asking how to securely remove a bitcoin wallet from your system (or the more extreme, remove any trace that Bitcoin was ever on a system ?)

Know that deleting a file does not necessarily delete the file (that's why they have "undelete" tools). So if you had a wallet without passphrase encryption, and then you delete that wallet.dat, there are ways of still recovering the keys. There's even a nice utility to scan your hard drive to find it:

I have made 20+ back ups of my wallet.dat, encrypted them in trucrypt containers made another 20 backup of that container, and emailed them to 5 different email accounts, and some other backup devices.

Great. But why would you delete it then?

So essentially just the wallet.dat has to go

What is it that you are trying to do?

The wallet.dat is a needed file. It should be backed up. The wallet.dat backup will only be useful when it was backed up when the client has shut down properly first before the backup operation occurs.

You generally don't want to be deleting anything.

what about that log.000000001 files
and db.log
and peer.dat

The log files may be needed if the database was not shut down properly, so you probably don't want to delete those.
Peer.dat stores peer nodes, and while you can delete that your node will recreate it by discovering nodes. There can be instances where not having the old peers.dat could be less secure than letting it access peers it has previously discovered.

ALSO where else on the Hard Drive/OS could anything be?
