Go into titanium backup. Click backup and restore. Find the app you wish to move. Long press and select move to SD.

 

That's strange. You should be able to uninstall by single tapping it and clicking "uninstall." You can always make a backup through titanium in case you need the app again

 

If you're looking to uninstall system apps, I recommend Root Uninstaller. If you are looking to move apps to your SDcard, I recommend Link2SD. Using App2SD only allows you to move certain apps to your sdcard -- others that are set internally to not be allowed to move to sdcard will not move. With Link2SD, you create an ext partition on your sdcard, and dynamically link all your apps (system, tagged not-to-move, etc...) to your created ext partition on your SDcard.
Google Link2SD and read up on how it works to better understand it before installing to make sure its right for you.

Good Luck!

 

I believe this requires req's cwm (but I may be wrong). If you have it do the following. Make sure you have a backup of your SD on a computer; partioning your SD reformats it. Enter cwm. Go to advanced and click partion. Select the amount you wish to partion. After that You can restore your items onto the SD. Once rebooted go to link2sd and click ext4
