All at one time

Hello all. This is my first post on here although I read the thread periodically to get ideas. I currently own my first Mustang which is a 2006 Auto Convertible Premium w/ Pony Package. I got it used in July of last year. It is all currently stock and am looking to do a couple of things to it while just sits in my garage and I watch the snow fly. Just to let everybody know, it is not a DD and is mostly used to go golfing or dinner on nice days with a mix of driving through towns with stop signs and 2 lane country highways in between the towns. As it is not driven everyday, I am not worried about gas milage as I only have to fill the tank once every three weeks right now. I am pretty sure at this point that I will have this car for a few years as we are buying my wife a new car and since this is the "toy" I will not be able to get anything else until her car is paid off. Following that I would like to have a little more jump off the stop signs and have a little more fun with throttle on the country highways.

The three mods I want to complete are: CAI, 4.10 gears, and exhaust. I know there are lots of threads about each one of these items individually, but I was wondering since I would like to do all three at the same time, if there is anything I should be looking for in particular for certain brands that go well together. Also, since I will want to get a tune as well, I know you can get some better pricing buying the tune as a package with the CAI or gears and was wondering if anybody knew if I would be able to specify everything I am doing so I can get one tune for all of the mods.

Thanks in advance for any input.
