If I have my fighter take Improved Critical with the Composite Longbow does the threat range increase from a Natural 20 to 19-20?
Yes
Yes, Improved Critical: Longbow gives you a 19-20 x3 crit with a composite longbow. Out of curiosity, why would you think it doesn't? Not trying to put you down, just trying to figure out where the logical disconnect is (because it may solve other questions for you as well).

I didn't know if it did or didn't. I've never created a character with this combinatioon before.
The way it works is all weapons & weapon like spells have at least crit range of 20. So that includes spells that require either a touch attack or a ranged touch attack.
So thats a range of 1, when you consider a feat or enhancement that increases your crit range by doubling it, you double the range of 1 (getting 2) and then the top two digits on your d20 now represent your crit range [19-20 for a range of 2].
So consider a Falchion which crits on 18-20. Thats actually a range of 3 so a improved critical for falchions improves the range to 6 meaning it threatens on 15-20!
