Two questions: Will a clean install speed up my machine? Any suggestions on how to streamline restoring all the OS and app settings from prior to the install?

I restarted it a few times but nothing. This chimed twice and I let it start up. Then I was still not installing. I then tried command R one more time and then it started to install.

At this point, you can manually copy your user data from the clone backup back into your new user folder. When it comes to restoring data for apps that are not document-centric, like iTunes, iPhoto or Mail, you need to find and copy the data from your backup to the same location on your new drive.

For other apps, you may need to search for instructions on where to find the data and preference files. At this point, you can start reinstalling any other applications you might have had installed. Do not try to copy them from your backup. Reinstall them from the original disks, or download them from the original source.

Erasing is sufficient, there is no malware that can survive that. Malware would have to somehow embed itself into the hardware such as in the firmware in order to survive a hard drive erasure.

Is there a straightforward way to accomplish that? You can download the Mountain Lion installer, then make a bootable install disk out of it and use that to erase the hard drive and install ML. If you make a bootable install disk according to those directions, then you can install in an offline situation.

Search for: Step 1: Back up! Step 3: Reinstall This step is pretty simple — just follow the directions to reinstall the system on the newly-erased drive. Step 4: Update Once your system restarts successfully, you will need to be sure that it is fully up-to-date. Step 5: Reconfigure Once your clean, new system is up and running and fully updated, work on getting all the settings back to the way you like them. Step 6: Import data selectively! Step 7: Reinstall applications At this point, you can start reinstalling any other applications you might have had installed.
