302 Emissions problems...

I failed the emissions testing awhile back, and after it did i took it to a shop to have a tune up and engine diagnotics test run. They found a bunch of stuff i need to replace and what not. They told me i need to replace my EGR valve, EGR valve position sensor O2 sensor and bunch of other stuff but those 3 are what is mainly affecting my emissions, right? I dont have mad cash flow or anything right now, but do you think if i replaced my O2 sensor for now, will it make any difference? I was thinking of getting a bosch but i dont know what would be best. I really need to know as i will probably be buying one today. Thanks for any help!

Oh and i also forgot to mention i need a new cat too, and was thinking about going with a catco. Does anyone have experience with the catcos? I just dont have excess to a welder right now to have it welded on. So i might still go with a O2 sensor right now. (but than again i dont even have my old cat on it anymore lol)

My truck is a 1991 F150 4x4 Nite with the 302 with a little over 105,000 miles....

Alrighty since nobody answered i just went ahead and bought a Bosch oxygen sensor. Ill be putting it in tomorrow, but the dude at autozone said i need some typa grease or sumthin on it. I dont know what hes talking about but theres already some typa grease on the threads of it so maybe thats what he was talking about. Does anyone know what hes talking about lol?
