I would go Beretta 92A1 and get a 1911 at some point. Particularly since you already have some 9mm ammo.
92A1 is on my list.
You can start getting 45 ACP and later buy a nice Sig 1911.
Skip the 92 altogether and get a cz or a sig.
Unless you have bigger hands with long fingers, I would stay away from the Berreta 92. Even with thing grips, the reach is too big for me and most people I know. Therefore I recommend the 1911. Remington, Ruger and Springfield all have nice 1911s for under a grand. There are other brands out there made in the Phillipines at a good price that are quite good also.
