The last of those issues was with the appstore. I had two applications that needed an update and every time I would try to update them I would get the following: "The product distribution file could not be verified. It may be damaged or was not signed."
So for those who are looking for an answer to this problem, bring up the good old command line and cd to '/var/folders/' from there your experience may vary! In the sub directories in that folder, you will need to find one that multiple levels down will have 'com.apple.appstore' as a directory. Once you have found it, delete it i.e. 'rm -rf comp.apple.appstore'. That fixed it for me I was able to update my apps again!
Man terminal window and command line stuff I feel so powerful again.
