Disk utility doesn't open, trash works incorrectly.

Question

After updating to 10.7.3 I have noticed that Disk Utility no longer opens. It pops up into the utility bar for a few seconds, bobs up and down a couple of times, then disappears. The next time I click on Disk Utility I don't even get that much of a response. It just doesn't open. No error report, no pop ups saying that it can't be opened - Nada. I can't use disk utility AT ALL anymore. I've tried Zapping my PRAM, but that's about it.
The other thing I've noticed is that any time I put something into the Trash Bin it automatically tells me that it will delete the item - it doesn't sit in the trash bin like it used to until you manually delete it. The only time I can get it to behave normally is when I am using an external drive and I put something from the external drive into the trash bin.

Repairing the permissions of a home folder in Lion is a complicated procedure. I don’t know of a simpler one that always works.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
chmod -R -N ~
The command will take a noticeable amount of time to run. When a new line ending in a dollar sign ($) appears below what you entered, it’s done. You may see a few error messages about an “invalid argument” while the command is running. You can ignore those. If you get an error message with the words “Permission denied,” enter this:
sudo !!
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
Next, boot from your recovery partition by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the recovery desktop appears, select Utilities ▹ Terminal from the menu bar.
In the Terminal window, enter “resetpassword” (without the quotes) and press return. A Reset Password window opens.
Select your boot volume if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select  ▹ Restart from the menu bar.
