If your car hesitates or has slow acceleration, then it can't be anything other than your engine and/or transmission.
The ticking sound is indicative on a mechanical failure, as opposed to an ignition/fuel system problem. (Though it can be both)
You'd have to describe the "Ticking" a little more for me to attempt to narrow it down.
When your engine's valve-train becomes excessively worn, and/or you experience a loss of oil pressure, you'll hear a ticking sound coming from the top-end of your motor.
If your "Ticking" sound is more of a metalic "clicking", then you could have something slipping in the transmission. (I'm no tranny expert). Such as your torque converter could've failed internally, but I've only seen that happen on extremely high-horsepower applications.
Maintenance will depend on how you've previously maintained your car. If you've kept up with all service intervals, then you won't need to come out of pocket with too much money.
Besides a regular scheduled tune-up and fluid/filter changes (engine/transmission), at 80,000 miles, you should also have your ball joints and suspension bushings checked and lubed if necessary. Your rear-end fluid should be changed. All rubber hoses and belts should be inspected and replaces as necessary.
