The President of the U.S. signed a bill for a city program? Me thinks your information is incorrect (and not just on this particular point).
As far as the other items listed in your post:
Bush has no control over what kind of rally any gay or lesbian group decides to hold. Apparently it wasn't very big - it sure wasn't mentioned on any news shows or in any papers I read.
I doubt Bush has had any time to even think about reversing policies put in place by Clinton re: gays. Seems he's been a bit busy lately fighting the war on terror and dealing with the economy. This argument doesn't hold any water with me.
As to the appointments you mentioned, I will say again, it does not appear he's appointed any to positions from which they can significantly impact the political/moral landscape.
