Ok, I'm not sure if nobody replied because they didn't uderstand what I was asking, or if they didn't know how to help. Either way it doesn't matter because I figured it out

I wouldn't usually make another post here but this is really cool and I think what I did should be explained in case someone else wants to try it (and I'm pretty sure the advanced skinners already know how to do this so please bear with me).
Anyway, specifically what I was doing was adding skin options into my custom_SkinSettings.xml so that I would be able to have the choice of how I wanted my top bar to look:
http://pastebin.com/ASbH6JUa (also did the same thing for BreadcrumbFontColor, BreadcrumbHomeIcon, and the TopBarColor was already done when I got the skin originally)
So now when I enter "skin settings" in the skin I have the option to chanage these things from a GUI standpoint. This is where I was when I originally posted my question, and thus the code that I was asking about previously. The problem was that there were numerous accounts of that code for TopBarColor, BreadCrumbBackgroundColor, and BreadCrumbFontColor throughout my 720p folder, and they were all "<include>" which stay in memory until the skin is reloaded or XBMC is restarted (these tags eat up memory). This is the cool part, and I think it might be what Wannabgt4 was talking about with "incluception" but I'm not entirely sure. So the main problem was that the code was mostly in my includes_Breadcrumb.xml file (font color includes and background color includes plus
http://pastebin.com/gnUt3RuN), and
<include condition="foo" file="includes_foo.xml">foobar</include>
doesn't work for several lines of "skin.string" code, not to mention the fact that I ended up with 100 or more extra little <include> tags after I was finished with my customization. What I ended up doing was making a new .xml file, moved all of the related code to one spot to make another "<include name=" (to avoid having to include everything from includes_Breadcrumb.xml file just to get what little i wanted out of it) and created this
http://pastebin.com/XS1ygaez (for TopBarColor, and FontColor as well) so that i could end up with these:
<include condition="skin.String(BreadCrumbBackgroundColor)" file="includes_BreadCrumbSettings.xml">BreadCrumbBackgroundSettings</include>
<include condition="skin.String(BreadCrumbFontColor)" file="includes_BreadCrumbSettings.xml">BreadCrumbFontSettings</include>
<include condition="skin.String(TopBarColor)" file="includes_BreadCrumbSettings.xml">TopBarColorSettings</include>
These replace the relevant four lines of code and take away from the RAM eating

Soooooo, long story short I basically just created three more <include>'s in the skin, but I wasn't sure how to go about doing that with a "skin.string" command. Sorry for such a long post, especially if this is common knowledge...but hopefully someone can benefit from this along the way---
