Michael, I believe you are mixing some things. I'm also a beginner to CMSs and I am currently reading Real World Color Management. Is is really a great book and it cleared many questions I had.
For what you want to do you need 2 profiles: one is the input profile - you get that picturing a target and running that through a profiler (take a look at Lprof for that, its open source and is said to deliver very good profiles), the other is any standart RGB profile as you said (that would be ProPhoto, sRGB, AdobeRGB,...). Profiles for standard RGB color spaces are shipped with operating systems, apps, or downloadable on the web - so you do not have to care about these, just have to find them:) Once you have the profiles you would create ONE transform out of TWO profiles: LCMS does exactly that. At last you would then apply the transform. Things can get a lot more complicated as you look at which image manipulation works best in which colorspace... and which is then the most appropriate colorspace for your application.
