It seems law schools are a little more forgiving of low GPAs when the low grades are older and you have a strong LSAT. Still, some schools may have a 3.0 floor for GPAs. Look around on Law School Numbers (
http://lawschoolnumbers.com/) to see who got into schools you're interested in with a similar GPA. With a 165+ LSAT, you will still have a good shot at lower T50s.
As for which grades are included: all grades that appear on college transcripts granted before you received your first bachelor's degree. So, if you took college classes in high school, those count. If you got an F but retook the class and the F remains on the transcript, the F counts. If you got an F but retook the class and the F no longer shows up on your transcript, the F doesn't count. If you got a second degree or took classes after you received your first bachelor's degree, those don't count. (I promise it's not as complicated as I just made it seem...

)
You'll also need to write a GPA addendum to be included with all your applications; it'll be pretty straightforward (young & foolish, later grades much higher, etc....maybe leave out the drunk part, haha). Look for threads on/by "splitters" to see how those with high LSAT scores / low GPAs fare.
Thanks for your service and rock the LSAT!
