Welcome to the toolset! Assuming you managed to get it installed and running correctly, you should be looking at a screen similar to the above.
I'm not going to attempt to give an in-depth explanation of what you're looking at, as there's already a quite thorough overview on the Toolset Wiki.
But in precis, we've got a preview window (the large grey area) where we can have multiple tabs of resources open. We also have a log window at the bottom left which will sometimes show us information we need to see, usually when we're either doing some sort of processing on a resource or are posting it into the game for use.
To the right is the "Palette" window which is an organized view of the thousands upon thousands of resources needed to construct the game. You'll note that the resources are presented in a foldered view, with the folders named after different major chunks of the game. This usually makes it easier to locate specific items; you just have to be able to remember what area/quest line they were part of. There are, of course, exceptions, but thankfully that text box in the palette window allows us to put in some text that will be used to filter the results. So if we're not sure where something might be found, we can try sticking in bits of its name to try and narrow it down.
Underneath the palette window is the Object Inspector, where detailed information about the item we currently have selected in either the palette or our preview tabs will be displayed. This information will be greyed out, as shown above, when we're in a mode where we can't edit what is shown. Individual lines of it can also be greyed out if that line of information cannot be edited from this particular view.
And now that we have some basic idea of what we're looking at, it's time to move on to attempting to make a very simple modification to the game.
