Well, that's basically what this is. Also, if you haven't already, be sure to give the manual a quick look! (it's in the game directory) It's rather nicely written.
I'm personally fond of these sorts of walkthroughs, as well. Just playing through a single game according to it's direction helped me get a feel for how the game played.
From there, check out the TA 101 thread, and the galciv wiki.
