I just bought the treadstone turbo kit and I was wondering what would I need to upgrade my fuel system so Iwon't lean out or run too rich either. What kind of injectors should I use and what fmu, fuel pump?

There's a whole bunch of answers to this it depends on what your plans are for the future, how much you're planning on boosting etc.
Definetly get a Walbro 255lph fuel pump, ($95-$100 shipped ebay and other places)
If you want a regular fmu then get a vortech 12:1 fmu
You can also get the vortech SFMU (good if you wanna upgrade injectors) ($100-$325 can get for cheap used here and ebay or new on places like summit racing) This will also require you running a return line assuming you have the late model fuel system I'll get the link in a minute with details, its on the main page. Edit: here's the link http://www.2gnt.com/nuke/modules.php?name=Sections&op=viewarticle&artid=82 You may also want to upgrade the return line to -6an instead of using -4an as in the diagram, it will help you lower your idle fuel pressure with the sfmu.
For under 7psi you don't need to upgrade your injectors, but may want to so you don't run such high fuel pressures If you're planning on running low boost for a while and have a stock bottom end go with accel 30# injectors, you can also get ford injectors if you want, search ford injectors or ford greentops hear and on ebay.
Then if you're going all out built block and high boost start researching the megasquirt and the hahn portfueler
They'll help you out whether you have the 95 system or the late system. Now after looking, I'm guessing you have the 95 b/c of your username
Also if you can afford it, look into getting a Wideband O2 Sensor, even better, one with logging capabilities.
