When your car wont start to find out if its the starter, have someone try and start it and tap lightly with a hammer/wrench, or a rubber mallet. The vibration will either click the solenoid, or jar the connector together and the car will start, just dont turn it off. Starters are one of the easier repairs to do yourself check out the cost of the part and maybe do it yourself, it should only take a couple hours in the driveway.
As far as the ticking sound, I cant tell you because I cant hear it, but make sure theres a good oil level first of all, and that the car keeps positive oil pressure just to be safe. To see if its something internal that may be a bigger problem, take a long screw driver and hold the tip against the cylinder head areas and out the handle to your ear, like youre using the screwdriver as a stethescope, that way when the sound is louder youre closer to where it is.
