Answer 1

That's got to be the cleanest report I've seen, so I have nothing to offer from the report to help with your Beachball issue. Suggest you check a few of these ideas: Macintosh OS X Beachballs!
However I do have a few update recommendations:
Java is seriously out-of-date, so I hope you don't have it enabled in your browsers. To update to Java Update 51 open System Preferences and click on Java to open the Java Control Panel. Choose the Update tab and follow the instructions there or download from Java.com.
Silverlight from Microsoft has some sort of security issue (probably Windows) and should be updated from Microsoft.
You don't need "com.apple.CSConfigDotMacCert-[...]@me.com-SharedServices.Agent.plist" since MobileMe was discontinued. To find it hold the option key down and select "Library" from the Finder's Go menu. Now look in the LaunchAgents directory (folder), find that file and drag it to the trash. This should not be causing you any issues whatsoever, you just don't need it any more.
Your hard drive will fail sooner or later (average life about 3 years) and probably quickly, so you need to have a current backup. If you don't like Time Machine for some reason, then make certain you have an alternative backup system in place.
Lex usually comes on a bit later, so he may have some other ideas for you.
