UV Unwrapping is not something that exists for SketchUp yet. But Whaat has created a plugin that bridges SketchUp with third party mapping utilities. http://forums.sketchucation.com/viewtopic.php?t=23725
It's a map I created my self. You can find better ones if you google for UV mapping test textures.
I've been experimenting with UVTools & UVToolkit since I posted my question and starting to build a comfort level. Appreciate the quick response, UV Map, and link to UVTools.
Best,
Hi thomthom,
Firstly, a quick thank you for all of your contributions. 
I've been experimenting (aka still learning) with SketchUp Standard over the last few weeks and have built several models of buildings (inside & outside) - no materials/textures applied at the moment. I now need to create/fix/clean the UV Map before I can export these models and came accross this thread in my search for the tools to do this.
A few questions I have are ...
Q - Is there an additional plugin that I need to take all the parts of a model and flatten them out to a 2D-plane in preparation of UV Mapping? I need to create a single diffuse (texture) image which contains all of the model parts so that i may be altered later using a graphics/paint application.
Q - Where can I find the sample "UV" image that appears in your YouTube demo at Post 1? I looked in the .\images folder and did not see it. Tried finding a "checkered" or "color grid" pattern and haven't had much success on that front either. I'm guessing these mapping images aren't standard issue. 
Appreciate any reference links/info.
