Template and ?php echo question

Hi All
I am new to all this, but am trying to learn as I go!
I have been modifying the stock template and am about 90% of the way through the changes I need to make.
I am having a little difficulty with a few changes, and one in particular that keeps cropping up.

The "?php echo" function that is all over the code of the template. For example:

<a href="<?php echo $home; ?>"><?php echo $text_home; ?></a>

This is the menu item 'HOME' in the Open Cart source code. The way I understand it is that this line of code in the "header.tpl" file is looking the the "$text_home" somewhere in one of the files to find out what to display. By default it displays the word "HOME". My question is where is this word "HOME" being pulled from? I would like to change it to say "STORE HOME" as I already have a "HOME" for my website, and want to distinguish between "HOME" and "STORE HOME".

I have also come across the need to find what the various "?php echo" functions are pulling from across many of the different sections of my site.

For example the code "<?php echo $text_latest; ?>" brings up the words "LATEST PRODUCTS" on the store home page. I would like to modify this to pull up the words "OUR PRODUCTS".

So far my store is looking like this:

Any help would be greatly appreciated.

Change Home to Strore Home.
