purchasing an x calibrator 2 or 3 and picking a tuner. you also would need a laptop and cables to connect from xcal to laptop to datalog so your tuner can see what he is working with. it also helps alot to have a wideband air/fuel ratio gauge so the tuner can use the input from that to further tune your car. using a flasher in combination with datalogging is the same thing as getting a dyno tune except the road is your dyno and the tuner can be on the other side of the world and tune your car.
tuners to choose from
those are really the only three worth mentioning that do the job for a decent price and do the job well. tom (1turbofocus) from focus-power is the guy i do business with because he gives free updates. say your car is stock now but you plan on adding boost (turbo, nitrous, supercharger) in the future. pay for the boost tune, which is more expensive, right now and he will tune your stock car. add more mods and he will re-tune it for nothing. finally put boost to it and once again he updates the tune for free. it is cheaper for a naturally aspired tune but if you boost in the future you have to pay for the tune again. all the other tuners out there charge to update a tune unless they are the ones that screwed it up in the first place.
if you have an automatic or SVT focus that is stock then a tune will make quite a noticeable difference. if it is a stock standard focus with manual tranny then you may not notice anything at all.
with the flasher you arent limited to just loading tunes into your ecu. it gives you the ability to read DTC's (check engine light codes) and clear them, you can tweak spark timing, what temp the cooling fans kick on, calibrate your speedo for different size tires, adjust the rev limiter, adjust the speed limiter anywhere from like 25mph all the way to taking it away all together if you want, you can adjust fuel trims to a degree as well as many other things that im sure im forgetting about. a flasher is a very nice tool to have around. and you can use it to read DTC's on pretty much any ford and mercury. i personally have used it on a mercury cougar, ford ranger, mustang, and f-150.

tom's first time in Vegas? PRICELESS!
