1.  google chrome will stop supporting linux lite in march 2016.  what will this mean to us?

No, Google stops support for 32-bit Chrome. This means that, if you're running a 32-bit system, you will not get any updates for Google Chrome beginning from March 2016. This is reasonable since today's systems are 64-bit. It is not only Linux Lite, also other 32-bit Linux distro's ar suffering this issue. What does tis mean for a 32-bit user? Easy and simple, with each new Chrome update for 64-bit systems only, the 32-bit Chrome version will be more and more insecure to use. All security bugs wil not be updated.

2.  how do i get chrome to recognize my microphone?

I think you want some websites to recognize your microphone? Can you  explain us what you already tried yourself?

3.  i did an update and now i have an app called nepomuk cleaner.  what is it and how do i use it?

Did you installed any KDE application? Nepomuk is part of KDE which will be installed if any non-KDE user installs a KDE application. Else there's no reason to get Nepomuk in a Xfce environment.

Else there's also the possibility that Nepomuk was installed when you installed an application called zeitgeist or zeitgeist comes pre-installed (not sure about this).

4.  is there a linux alternative to windows compatible freemake converter?

5.  does linux need ccleaner or a defrag program?

Not really no. Basically you must ask yourself the following 2 questions:
1) can you run few commands for occasional package cleaning, manually deleting browser history etc.
2) do you want to run from place to place and you just want one tool to rule them all where you can clean up all the suggested things in one (or few) click(s).

Linux alternative for CCleaner is Bleachbit, another tool i'm using is deborphan. Last mentioned tool requires a deeper insight in Linux and is more meant for the experienced user! Bleachbit works with a GUI environment and has an easy-to-use interface.

There are some terminal commands which cleans your system, check here: https://sites.google.com/site/easytipsfo...n-up-linux
