The guy at work has absolutley any idea about conti's. You couldn't ask for a better car to do a tune up on. Everything is right on top of the engine. If it is running good you might not want to change to much. But you could do your plugs, make sure you use antisieze on plugs and dieletric grease on your coil packs (their are no plug wires on your car) Air filter, cabin air filter, pcv valve. You could also do a trans flush and filter also IF AND ONLY IF the trans fluid has been changed regularly at every 30,000.
Plugs, oil change, air filter, pcv valve, and cabin filter will run you around 80-85 dollars. You can do all these by yourself, it requires no real mechanical knowledge. Trans flush and filter will run you around 245 at a ford's dealer, DO NOT take it anywhere else, ford will warranty their work.
Brakes will run you about $100 a set (front or back) easy to do yourself, you will want to purchase a cube tool to run the back calipers in. Coil packs are kind of pricey but if you don't have any problems with them you can let them go.
Good Luck and welcome to LVC!!!!!!
