Timing is easy, if I remember correctly, you pull the spout wire, then loosen and twist the distributor while reading the timing with a timing light, set your desired timing, then tighten down the distributor and reconnect the spout.
What is your budget like?
If you just have a couple hundred, a set of gears will give you a seat of the pants increase. A ported intake (by tmoss) is inexpensive and effective. Underdrive pulleys are good unless you have a huge stereo and need all of the juice you can get. Since is is a female owned car, I assume it's an automatic, they work well with a shift kit and a high stall converter. If it's a 5 speed, an aftermarket shifter works better and can save 3'rd gear. Shorty headers and a better H or X pipe will add a bit, an offroad pipe will add more. There are several things that you can remove to help your car's weight.
After that stuff it can get pretty expensive. Superchargers, turbo's, Heads-cam-intake (HCI), strokers, 351 conversions, 460 conversions. Then you start to break stuff, so add a built transmission and rear end.
