I would have to say Exhaust and a lid, because I am in the same ball park as you but I have a 99 Z28 with 20,000 miles on it and I just got a Lid and Loud Mouth exhaust

 

As for what to get. Simple boltons would include Lid, catback, Fast Toys Ram Air, Free ram air, long tube headers.

A few recommendations from me would be. Any brand lid with a filter (holley, amsoil, K&N, etc), you can find these at any of our sponsors

catback, depends on if you care about looks and what sound you want, loud sound try the loudmouth, great looks with a more exotic sound, try the corsa system. An F-body favorite is the Borla system, you can find these system at any of our sponsors

As for Long Tube headers, my recommendation would be the QTP headers from www.quicktimeperformance.com these headers are the best in my opinion and in tons of other people's opinion, do a search on these (also used to be called Grotts, but under new management now) You won't read about 1 person complaining, every other header out there someone has a complaint about it. These are what I will be going with.

as for springs, I would say give DMS a shot, they seem to have a good product, or you could try the eibach springs, but some people complain about those sagging, when you put lowering springs on, its not a bad idea to get some shocks. Good shocks are Bilsteins, Koni, Hal, etc. Also if you plan on lowering you going to need LCA relocation brackets, and an adjustable panhard rod, while your in that area, its not a bad idea to change the LCAs too, that'll get rid of your wheel hop. Also if you plan on headers with lowering, the QTPs make your choice even easier, a lot of LT headers cause problems with lowering, not these headers, they are amongst the best in fitment.

 

Just noticed you had an A4 too, you should look into a yank or vig torqu convertor. This mod will make the biggest differance in the way your auto performs. This mod alone can put you into the 12's with the proper tires

As for a stock SS, you should see anywhere in the 13's, could be low could be high, depends on the car, track prep, weather, etc etc etc.

And congrats on the new car, I love those SS camaros.

My plans are as followed, feel free to copy me. Some of these mods are already done.
Free mods, Lid (MTI clear), catback (corsa), FTRA (fast toys ram air), QTP LT headers with dual cutout Y pipe and cats, GW SFCs, LCAs, APHR, lowering, Chrome TT2 rims, drag radials, Yank TQ.

This should easily put me in the low to mid 12s
