Some updates take forever

To install, especially the reboot process. If interrupted you can pooch the system, and have to reinstall from scratch.

Use Software update to get the names of the proper packages of updates. You can download the Combo package which does solve problems caused by using the "individualized" updates.

The Spinning wheel can mean your drive is bad. Even if the HD is new, it doesn't mean that it can have many bad blocks out of the box. Try writing Zero's to your drive with the erase option in disk utility, this will re-alocate any bad blocks you have on the drive. Then try to reformat the drive and re-install your OS. If you have Tech Tools Pro 5, you can use that to scan your drive for bad blocks. If you have too many of them, I would return the drive.
